My adventure out west to race 24 hour mountain bike nationals led to a 7th place finish and lots of lessons learned for next year’s Race Across America. Here is all my heartrate data and a map annotating the course as well as a general description of the course. The lap times on my heartrate graph do not include time spent resting between laps, so this gives a better picture of how my legs/body were feeling on any given lap than the official lap times which include time spent in the pit between laps. One of the things I was really happy with for this race is that after an hour and a half of sleep, I put in negative splits on my last four laps. In other words, each of my last four laps was faster than the one before. That is very encouraging for RAAM how my body was able to recover and respond after such a short rest.

Annotated topocreator map of the entire course. One of the advantages of the topocreator map over Google terrain view is that it is very easy to pick out the high points on a course like this with all its gentle sloping. Click to enlarge.

This race was so well-organized by the folks at Zia Rides, and one of the great things about the course was having big red mile markers every mile on the course. This meant that you could break the course up into smaller sections and tackle each section independently – super important for a 24 hour race where you are looking for those boosts of achievement when you are super tired … so reaching the next mile marker meant you were one mile closer to the end of the lap. On the topocreator map above, I have labeled each of the miles in black M1, M2, etc…
We started the race out on the wide dirt road so that we would have a chance to sort out positions before the start of the singletrack. I had been worried all week that we would start in the campground under the finishing banner, which would mean a very short dash of 100 meters or so to the start of the singletrack before the dirt road. This singletrack was a climb through the campground followed by a descent to a bridge with a 90 degree turn entering and exiting the bridge – then more descending down through a cow field before a gentle climb up to the dirt road. When they announced during our pre-race meeting that the start would be on the dirt road, this was a huge relief that I wouldn’t be pressured to going really fast through the opening singletrack.

Still, it is tough to get everything organized for a 24 hour race and I didn’t hop onto my bike to ride over to the start at 11AM until after 10:30AM. Jake Wade (friend from ultracx racing) and I rode over past the start together and then out to the start of the singletrack and back as warmup. Even though we were back at the start by 10:45, there was already a ton of people lined up. So I started in the third or fourth row thinking that it was going to be tough to make up much ground before the start of the singletrack. Fortunately, I was on the righthand side and there was a 30+mph crosswind blowing from the left. I passed a ton of people and settled into line somewhere in the top 10 before the start of the singletrack.
The opening singletrack dropped down briefly before climbing steeply for about a quarter mile. Then it rolled along the side of a hill eventually making a 90 degree turn to head back down into the valley. But before hitting the valley, the trail went straight up a rock ledge. This was totally rideable as long as you had some momentum. I was worried that if you weren’t far enough forward somebody would goof this up and everybody behind would have to walk. I’m not sure if that happened or not because I was far enough forward that everybody could ride it. Dropping off the ledge on the other side was a dip down to a bicycle-specific cattle guard to take you into the long climb to the top of the course.

This climb started out very steeply but then rolled a bit before settling into a gradual gradient for several miles. The gradual climb was easy and non-technical except you did have to pick your line carefully to avoid riding over some big rocks. Those rocks were also rideable, but for a 24 hour race you are looking to save every ounce of energy and save your body from as many rock-jolts as possible … so you wanted to ride around those rocks instead of over them. The climb was about half-way over by the time you made it to the cat-tail pond where the junior course split off to the right.

After the pond, the course continued to climb through miles 6 and 7. Topping out for the first time shortly after mile 7, there was a gentle fast downhill with lots of sandy turns before a gradual climb up through mile 8. This process repeated itself several times through the rim trail until you finally made it to mile marker 10 which was the high point on the course and the start of a long gradual descent peppered with a short steep climb at mile 11 and a few other small rollers. The climb at mile 11 started out with a short rock slab section followed by a turn straight up a steep hill. I rode it every lap except lap 8 where I was so exhausted I walked the whole section (including the flat parts) just to change up the pace a bit and give my hands a rest from gripping the handlebars.
One of my favorite parts of the course was shortly after this short steep climb – the singletrack continued climbing for a bit before diving back down one more time into a gulley followed by another steep climb on the other side. I figured out in my pre-rides that even with the rocks and roots on the climb, your best bet for this was to fly down the hill and hit the gulley at full speed. You popped up over the rocks and were more than halfway out of the gulley before you even had to pedal. Almost immediately after this, you rode straight towards a property line fence. The singletrack followed the fence very closely for about a mile. Each lap I looked forward to this fence because it meant you had about a mile of easy, smooth, fun riding before the rocky section of the downhill and then the long “berma” section of downhill. I didn’t get any pictures of this part of the course in any of my pre-rides because I never wanted to stop to take one.
The first major jump on the downhill section came right before mile 14 (red mileage marker visible in the middle of this picture) and was followed immediately by a 90 degree turn. Early on when you were fresh you had to make sure to keep your speed under control so that you didn’t endo on the landing.
The strava segment for this long downhill is called “Berma” presumably because after the jumps you have a number of partially banked turns. The dirt was quite loose so you had to get your line right or risk having your wheel washout. I had a couple close calls during my pre-rides, but by race day had nailed it down pretty good. Once you hit the bottom of Berma, you basically had a 4 mile rolling climb to the finish. The rollers were pretty steep (both up and down) so you got to do a lot of resting on the downhill parts which made the uphill sections more manageable after you had been racing for a long time.
The last mile was some narrow, bumpy singletrack alongside a beautifully paved road. No paved road for the race course, however, with 18 miles of single track and just over a mile of dirt road for a grand total of 19.15 miles per lap. In this picture the righthand side is looking up towards the campground / finishing area and the left side is looking back down the final mile of singletrack alongside the paved road.
That takes you through a single lap of the course. I was fortunate to pre-ride the course four times during the week leading up to the race and then twelve times during the race for a grand total of approximately 325 miles of singletrack — easily surpassing any kind of all-time personal record of number of miles of singletrack ridden in a single week. The course was perfect for a 24 hour mtb race, fast, diverse, safe, fun, and challenging. I’m very sad that USA Cycling is dropping this event off the national championship calendar, but the event was so well run we are definitely going to have to make this a future family vacation sometime in the next few years … maybe even next year!

A post about climbing the ridges in Birmingham wouldn’t be complete without my favorite ridges southeast of town – especially the two high ridges on Double Oak Mountain. I rode out there today armed with my camera and ended up taking more than 50 photos. I picked out the best ones and created a topocreator map to highlight the ridges southeast of Birmingham.
Two screenshots merged to form a complete ride profile (10 mile, 250ft scale). The numbered ridges and creeks are labeled on the topocreator map below.

After three weeks of traveling out west and enjoying some really amazing riding and sightseeing with the family, I have been enjoying a week of riding back in Birmingham. Today’s ride typifies the type of ridge riding that you can do here in Birmingham. I started out this ride with a loop on the side of Little Valley Mountain followed by a route crossing all the major ridge lines to Birmingham. Then I turned around and took a different route home recrossing the same ridge lines at different points. After a quick stop at home, I did a loop through Bluff Park bouncing back and forth between the two ridge lines on top of Shades Mountain. That last bit through Bluff Park is shown with ridge and creek crossings highlighted in the first elevation profile and map below:

Today was quite a combination of rides — hitting a new personal record of shortest distance to 5,000′ of vertical gain on the way into work and then hitting 5,000′ ft again in less than 30 miles on the way home from work. Both rides were pretty slow with lots of weaving on the steep parts and several roller coaster repeats. The best thing about the roller coaster repeats is that they are insanely fast in the 53×11 on the descents and then nearly instantly into the 39×28 — that’s a lot of wear and tear on the derailleurs. No wonder I have broken three front and one rear derailleur in the past year and snapped several cables.
Finally, here are the garmin screenshots:

I don’t know why I never thought of making one of these before for the Southern Cross race course, but the topography is really cool and it certainly shows in the maps below … enjoy! Also, I noticed while doing the maps that the course enters 4 different counties. With a slight route change, it could be a five county race!
Wrapping up a wonderful weekend of riding, racing, and climbing in the beautiful North Georgia mountains outside of Dahlonega that included the Southern Cross Ultracross race, I headed out for one last ride right after the nice breakfast provided by the awesome folks at the Hiker Hostel. My daughter’s church choir program was at 5PM back in Birmingham, and I really wanted to be back in time for it – so my original plan of 85 miles and 11-12,000 feet of climbing got scaled back to 65 miles and 9,000 feet of climbing.
Having thrown out my original route plan, I decided on a modified route that included 4 major climbs (Cat 2 or higher) and a few smaller climbs (Cat 3 or lower). I climbed Woody Gap from the R&R ranch and then proceeded backwards on the Six Gap century course climbing over Wolf Pen, then heading out to Jack’s Gap and taking the 180 spur all the way to the top of Brasstown, turning around at the top and reversing my course but this time heading up Neel’s Gap on US129. The final climb of the day back to the Hiker Hostel had the steepest gradients with a crazy steep driveway access road that climbs up and over a couple mini-ridges before turning into a dirt power-line trail with gradients well over the 30% that ended up getting recorded on my iBike.
