Gatlinburg Climbing and Crashing

Me at the top of the Clingman’s Dome tower, Gatlinburg valley in the background

Two days, 75 miles, one high speed crash, and over 12,000 feet of climbing! Read all about it below…

Day 1 – Cherokee Orchard Climb and Gatlinburg Bypass Loop
I just posted a few days ago about the awesome Double Oak Way 1500ft climb in Birmingham, and it is definitely an awesome climb. But if the Double Oak Way climb is awesome (which it is), then the Cherokee Orchard climb here in Gatlinburg, TN is beyond awesome.

Before I dig into my recap, here is my word stream of thoughts on the climb:

dark
deserted
bears
paved wilderness
narrow
cold
steep
silence
bears
narrow

And as the climb reached its crest, and the narrow two-lane road turned into a one-way paved path through the woods and eventually plunging back down the mountain, here are the next words that come to mind:

steep
downhill, finally
paved single-track
tree
steep
fun
amazing
tree
life
bridges
creek
tree
cold
deer

Those were the word summaries. Here is the recap …

We had a long adventuresome drive from Birmingham to Gatlinburg arriving late at night so we didn’t have the grand majestic view of the mountains as we drove into town. Instead, we arrived after midnight to beautiful Christmas lights, cold temps, and a hotel room that had accidentally been double-booked with another guest. So when the security guard gave us our key, there was somebody already in the room! After a few phone calls, the guard was able to get in touch with the hotel owners and find us another room. By 1:30AM, we were settled into our room and I began working on a few last minute things for the computer conference the next morning.

At 2:30, I set my alarm for 5:45 to get up and go for a short ride before the start of the conference. Even though it was only three hours of sleep, I was wide awake as soon as the alarm went off because I knew what was waiting – a nearly 2000ft climb up Cherokee Orchard Rd and a first-time descent of a one-lane, one-way scenic drive through the woods just outside Gatlinburg! This was a route I had planned out over a month in advance, and it turned out to be a really nice selection of roads around Gatlinburg with the centerpiece being the Cherokee Orchard climb and the one-way descent through the woods all in a loop less than 20 miles long with over 3000 feet of climbing.

I was out the door by 6AM. It was still very dark, and as I turned onto Cherokee Orchard road and headed up the initial slopes of the climb, I kept wondering if I would stumble upon a bear rooting around for food before daybreak. My small headlight that I was carrying didn’t shine very far. But I made it up the 3 mile initial part of the climb without seeing much of anything. It was cold and quiet (except for the creaking of my bottom bracket). By this point, I was 20 minutes into my ride and the pre-dawn sky was brightening a bit. I turned onto the one-way, one lane scenic drive road (speed limit 10mph) and continued climbing for another couple miles before reaching the high point at just under 3200ft (1900 ft of vertical gain from the starting point at 1300ft).

I started down the descent excited, but hesitant because of the steep drop-offs, trees, and sudden twists and turns. I decided that it was bright enough by this point to stuff my headlight into my back pocket since I might need both hands for hard braking and cornering. The descent was so much fun. I couldn’t let it completely out because this was my first time down the descent, and because I couldn’t see very well. In fact there were several times where I thought the road went one way and in fact it went the other way so I kept my speed in the mid to upper 20s. Because of the poor lighting, though, it felt like I was going twice that fast. And with so many twists and turns, it was just amazing. You literally were dipping and diving between trees on a paved path through the woods about the same width as the Lakeshore trail in Homewood.

Here is a picture of the paved path that I took the next day with a bit more daylight. Note that this is looking down a gradient of nearly 15%. You’ve got to be sure to lean the right way – no room for errors!
Paved path, one-way, one-lane descent off the Cherokee Orchard climb. This wasn’t even the narrowest or coolest part of the descent, but rather towards the very top. I wasn’t going to ruin the descent to stop and take pictures!

The rest of the ride was great, either up or down with very little flat sections. I made it back in time to get ready for the conference and help staff the registration table (I was on the organizing committee). The conference went great, and I was very busy all day so I didn’t get a chance to debrief the ride until that evening when I talked Kristine’s ear off about it at the Bubba Gump shrimp factory.

Day 2 – Clingman’s Dome and Cherokee Orchard Remixed in the Daylight
The 22.5 mile Clingman’s Dome climb is as epic as Cherokee Orchard is awesome. The sheer scale of the climb makes it difficult even though the average gradient is only 5%. The climb starts at an elevation of just under 1,300ft in Gatlinburg, TN before climbing up to a final elevation of 6,643ft at the top of Clingman’s Dome. The average gradient of 5% is a bit misleading though because it includes a steep mile long descent and several flat sections. So that means that the “uphill” portions are a bit more than 5%, more like 7%. The descent is also epic because of its length, even though there aren’t very many technical sections. I ended up wiping out on one of the more technical corners at the top because the corner had a sheet of ice on it only on the downhill side! In other words, it was dry on the uphill side of the road so I was caught completely by surprise on the descent when my rear wheel started to skid and down I went at 30mph, sliding across the ice on the road, across the ice on the shoulder of the road, and into a snow bank.

But before we get to that, let me take you through the day’s adventure. I set the alarm for 5:45AM again, because the traffic in the Great Smoky Mountains on a weekend is horrible. I was warned about this ahead of time a few years ago, and so whenever I have done the Clingman’s Dome climb, I have always tried to be out the door by 6AM. This year, I was out by 6:20AM and a little concerned about traffic. My concerns were misdirected though, as I should have been more concerned about ice and keeping my bike upright. There was actually less traffic this year than normal on the 2 hour climb. I’m not sure why, though, because when I came back down the mountain there was tons of traffic coming back up the mountain. I guess everybody must have decided to sleep in this year!

Let me step you through the climb. As soon as you leave Gatlinburg on Hwy 441, you begin climbing — pretty gradually for the first couple miles until you pass the intersection with Little River Rd. At this point, the gradient kicks up to 6-8% which it stays at pretty consistently for much of the climb. There are a couple sections that are flatter in the 2-3% range bringing the overall average gradient down to 5.1% for the first 15 miles of the climb reaching an elevation of just over 5000 ft at the Newfound Gap scenic overlook on the border of TN/NC. After a short flat section, you leave Hwy 441 and head onto the Clingman’s Dome spur and begin the final 7 miles of climbing (22.5 miles total).

The Clingman’s Dome section of the climb starts out pretty gradual, and you are totally pumped from having made it up to Newfound Gap. So your average speed kicks up a bit, but pretty soon the road angles up more sharply into the 6-7% range for about 2.5 miles before cresting on the backside of Mt Collins. It is not until this point nearly 20 miles into the climb that you can see your first glimpse of the top! Just as you finally see the top, the “climb” turns into a one mile descent in the 6-7% range. Keep in mind that this entire road is twisty with no straight sections. Very fun!

For the final push, you have to regain the elevation that you just lost on the fun descent. This is a pretty steady 6-7% two mile climb with amazing views to the east, and icicle covered cliff walls above to the right. Coming around a corner, you suddenly enter the massive parking lot for the top. When I did the climb Saturday morning, the parking lot was pretty much deserted which is another reason to start the climb so early. The final 300 vertical feet of climbing is compressed into about 1/2 mile making for an average gradient of 12.5% with stretches in the 17% range. Steep – but not as steep as South Cove Dr in Vestavia (220 feet in 0.2 miles) or stretches of the Double Oak Way climb! Of course those climbs here in Birmingham don’t come at the very end of a 22.5 mile climb!

As I made it to the very cool tower at the top with its circular wheelchair accessible ramp, I noticed that the tower was pretty full of people! I was surprised because I hadn’t seen very many people up until that point. It turns out that it was a boy scout troop starting out on a hike on part of the Appalachian Trail to mark spots that need maintenance. They cheered me on the final stretch as I raced up the ramp. The view is breathtaking, and I have included a few of the pictures below that I took with my cellphone camera and a few pictures that I took when we drove with the kids back up to the top at sunset.

Descending off Clingman’s Dome
The descent begins with the steep paved trail back to the parking lot. I was fortunate because there was only one family on the entire trail. That meant I could go a bit faster than other times of the day when the path is completely overcrowded and overrun with people. You still can’t go that fast though because somebody might dart out. Once you make it back to the road, you get to descend on a twisty, beautifully paved road with slightly banked corners. Very fun. After 7 miles, you make it back to Hwy 441 and continue for another 15 miles down the mountain back into Gatlinburg. Towards the top on one of the shaded north-facing side of the mountain, I ran into my problem with the ice. Besides the immediate pain of falling hard, I was very distraught that I might not get to finish the rest of the ride. After picking myself up and seeing that I wasn’t hurt and my bike appeared to still work, I took off again. I was hoping to catch up to the pick-up truck that I had been drafting at the time I fell.

The truck had gotten too far ahead, but I still enjoyed the rest of the descent slowing down at the only other spot which could have had ice. Once I made it past that point, I pushed my 53×11 the rest of the way down averaging 37mph for 6.5 miles! The descent is fun because of the novelty of its length, but for a speed freak like me it’s disappointing to max out at 43mph.

Cherokee Orchard Remixed
Once I made it back into Gatlinburg, I turned onto Cherokee Orchard Road and immediately began the Cherokee Orchard climb that I had done the day before early in the morning. I wanted to do the descent again in the full daylight. I knew that there would be more traffic. I ended up having to wait behind two cars at the very bottom, but all the other cars I came upon moved out of the way just enough for me to pass. This was sorta tricky because the road was only just wide enough to fit a single car through between the trees. I’ve posted a few pictures below from when I drove Kristine and the kids through after I finally finished the ride and we had breakfast. If you could find a time with enough daylight and few cars, that would be the optimal time.

Tired and exhausted I made it back over the final hills to our hotel to pack up, head to the nearby Glenstone Lodge for brunch, and then head up to Ober Gatlinburg to enjoy the day with Kristine and the kids ice skating, mini-golfing, alpine sledding, and chairlift riding before beginning our drive back home to Birmingham with a quick drive up the mountain, quick hike up to the top of Clingman’s Dome from the parking lot, and a beautiful sunset. All the pictures below are from that portion of our trip. Check them out!

The Double Oak Way 1500 (aka fun in the off-season)

The Double Oak Way 1500ft climb (medium version)
Huge version (5.9MB)

3D map of the complete Double Oak Way 1500ft climb

The Double Oak Way climb has been a favorite of mine since I first rode it a couple years ago after somebody at Tuesday Worlds mentioned that they had rode their motorcycle up it the day before. The very next day, I went for a ride out to Mt Laurel and climbed it for the first time. I had scouted it out ahead of time using topocreator.com and knew that the road would take you up over 1400ft, which is very rare for the Birmingham area. The only other climb I am aware of that tops out at over 1400ft is the Pine Mountain climb north of Trussville.

So anyway, my first time up the Double Oak Way climb was the summer of 2008. Since then, I have climbed it probably 20 times over the course of a couple years. Well, as I was working on the topocreator.com website last night (yes, it is going to go into real beta testing soon!), I stumbled across a topocreator map of the climb and noticed for the FIRST time that there was a small thick contour line representing 1500ft not too far from where the road ends at the radio towers. The towers are at an elevation of just over 1450ft, but less than 3/4 of a mile away was the opportunity to ride up to 1500ft. I immediately scanned the map to find the lowest point in the area to see just how big a climb I could make it. And it turns out there is a spot in nearby Chelsea at 475ft meaning that the total vertical relief was just over 1000ft. Plus with a few downhills thrown in throughout the climb, there is over 1700ft of total elevation gain in the 10.3 mile climb.

Today, for the first time I did the complete 10.3 mile climb topping out at 1502 ft. Let me take you through the climb as I remember it. First, I didn’t get started until later in the day, so I knew that the only way to make it all the way out to Chelsea and back before it got dark was to bee line a good portion of the route on 280. Once I made it to Chelsea, I promptly turned around and began the climb. You first go through the Chelsea Corners shopping center before crossing under a small railroad bridge where the road turns into onto Old Hwy 280, which follows a creek on a fairly gradual incline right between these towering cliffs on either side of the road and creek. At the top, I just missed the light to cross 280 so after a short wait, it was game on again to finish the climb. There are a couple of steep rollers as you head out on Co Rd 41 towards Mt Laurel. Then, once you make the right turn onto Double Oak way just on the outskirts of Mt Laurel, the real fun begins!

The climb hits you hard right at the beginning with a 0.6 mile stretch that climbs 389ft for an average gradient of 11.8%. There are a couple of short spots where the gradient approaches 25%! There is also a gate about 3/4 of the way up this part of the climb, where you have to dismount and literally climb through the middle of the gate between the thick bars to keep cars and motorcycles out. Remount just in time for the 20-25% “am I going to fall over” 1/10th of a mile stretch which I went up at 7.1mph (avg), 5.9mph (min), 9.2mph (max). The next part of the climb starts out with a short steep downhill followed by the start of the next section of the climb, which is a 1.75 mile stretch with an average gradient of only 2.75%. This is where the best views are, too, and it is so nice and peaceful to ride on a road without any cars at all! The only thing you have to worry a little bit about is deer. I startled three on the ride today narrowly missing one on the way back down!

The road kicks back up to 16% gradient as you make it to 1425ft at the top of this first crest. On the other side, is a super steep downhill (20%) that bottoms out before you immediately start climbing again at nearly a 20% gradient up to the radio towers. This is where I have turned around the past 20 times I have done this climb. But after seeing the topocreator map last night, I knew that I was going to do my best to make it to the 1500ft circle on the map! So I headed off-road onto what is probably a hunting trail (have to be careful about that, I tried to make a lot of non-deer sounding noises, i.e., whoops and hollers which was pretty easy since I was having just about as much fun as I have had all year on the bike!). I followed the trail which was mostly double track covered in leaves and even some grassy areas. I flew through this area which was fairly flat at 1450-1475ft before it dives down again to an intersection with what is probably a motorcycle dirt trail judging by the ruts and rocks. This was really hard to ride because the rocks were big and loose.

At the intersection with another trail, my memory was getting a bit hazy about where to find the final stretch back up to 1500ft, and I almost turned around thinking I had missed it when I looked up and saw another split in the trail heading up to the top. It was super steep, sandy in spots, rutted, and rocky in some spots so I wasn’t sure if I was going to be able to make it up the 1/4 mile trail with max gradient of 18%. But as I got further and further and hadn’t fallen off yet, I thought maybe I could make it to the top. Alas, I got stuck in a rut not 50m from the top and decided it would be faster just to run the rest of the way up. At the top, there was another path off the trail that led to some rocks where I got a few of the pictures below. I had made it to 1500ft. Total time for the climb – 10.3 miles in 41 minutes for an average speed just under 15mph!

It was beautiful, and the sun was getting ready to set so I couldn’t enjoy it long. Took a few pictures and then booked it back through the trails, over Hugh Daniel, back across 280, and all the way home just after sunset. It was an amazing awesome ride. Check out the maps, pictures, and data below. Also, the bottom map shows the climb in relation to several of the other climbs and high points in the area. So who’s going to go with me next time??? I can’t wait to tour guide this climb to some adventurous riders!!!

End of the year epic sassafras mountain ride

End of the year epic sassafras mountain ride (2D)

3D view of the major climbs on this year's ride

It has been an annual tradition for me for the past 15 years to end the season with a truly epic ride. During my college days, that would involve a 200+ mile ride in the mountains of North Carolina, South Carolina, and Georgia. In my older and busier days now, I have shortened the ride down to about 100 miles, but still with awesome climbing in my college playground of the NC/SC/GA tristate area. This year’s ride included two major climbs — Whitewater Falls and Sassafras Mountain — with countless smaller hills in between adding up to over 11,000 feet of climbing. And at 108 miles, it was a few miles longer than the past few years as well.

Check out my power and heartrate stats below: I love that my highest heartrates are on the crazy awesome descents!!! Leading into the long descent from Sapphire down to Rosman, I saw a big truck coming up behind me on US64, so I hammered the last 200 meters or so to just stay ahead of it before the start. Then he didn’t catch me until 15 miles later just before I turned onto US178 to head into Rosman! Plus for Sassafras Mountain, there is only one section where it is safe to really let it out, but that section happens to start with a 20% ramp before settling down to a nice 10-15% downhill gradient. I maxed out at 59.4mph staying above 50mph for almost 30 seconds! It definitely felt like the fastest I’ve ever been on a bike – especially since the road is rough. The bike feels like it is going to break up underneath you.

Greenville Fall Cycling Extravaganza Day 1

Quick update from Greenville, raced hard tonight, made it onto the podium in 3rd place. Small but tough field! Strong teams from Hincapie and Subaru (3 riders each), and then a lot of strong solo riders, too. I made it into a couple good breaks, but with the downhill backside of the course and lots of strong riders not wanting to see the race go up the road, it always came back together. With maybe a lap and a half to go two riders slipped off the front and got a few seconds on the field. With half a lap to go, I attacked and was closing when I clipped a pedal hard in the last corner and thought I was going down. I still had a pretty good gap, though, so I was able to hold onto third with only one rider passing me before the line. I believe it was Darius from Myogenesis who passed me just before the line, and congrats to the Hincapie rider (and the whole team) who won. Great race. I think it was Wilmar from Hincapie taking a well deserved win.
