Sandy Springs crash, videos, and race report

Summary – racing well, but missed break which lapped the field. I was working hard to stay at the front with 2 laps to go when my front wheel started to slide out on the fast downhill turn #3. I straightened up to stop the slideout, but that meant that I wasn’t going to be able to finish making the turn at 32+ mph. I ended up slamming into the barriers shoulder first at 32.3 mph according to my iBike. Here’s the same explanation in video form at the hospital:

I am incredibly sore on both sides and the back of my neck. Here is a picture showing the bruising and swelling around my neck and where the helmet straps cut into the skin. Same thing on the other side of my neck. Ouch.

Dilworth USA Crits power/heartrate data and quick report

Tough race today. Still not feeling 100% but happy to survive with no cramps and wrist not as sore as the night before. I started midpack and then stayed there for most of the race, drifting towards the back all too often and then fighting my way back towards the front. The key feature of the course was a tight greater than 90 degree turn at the bottom of the hill to take you back up to the start/finish line near the top of the hill. This is the source of all the power spikes in the data — accelerating out of the corner and up the hill. Kristine got some great video, and I will have those uploaded by the morning. Here’s a video of the finishing sprint:

Spartanburg power/heartrate data and quick race report

Fun, fast course last night in downtown Spartanburg, SC. This was the fifth of seven races of the USA Crits Speedweek. Very smooth race on a short four corner course. The start/finish stretch had a short section of brick cobblestones and a few manhole covers. This was the only part of the course that was rough. Everything else was super smooth, and we flew through 70 laps in 1 hour 15 minutes for an average lap time of just over 1 minute.

I started mid-pack and worked my way towards the front, but got swarmed in turn 3 a couple times and found myself back in mid-pack. Then with about 15 laps to go, UHC and Kenda started to set up the lead-out trains for their sprinters. I was still able to move up and passed people as they came off the front or sat up. By the end, I was able to finish 44th. I was happy to finish because I wasn’t sure if my sore leg was going to cramp up and how my wrist would hold up. Both were fine, and I was happy to get some finishing points for the series.

With no crashes, flat tires, or broken spokes, I was able to record power data on my iBike for the entire race.

Athens, Roswell power and lap data

I am too tired to write up my race report tonight, but I wanted to go ahead and upload my power and heartrate data. I’ll be working on a full race report tomorrow!

Athens Twilight heartrate summary

2011 Athens Twilight heartrate data

2011 Roswell Criterium heartrate data

I had crashes in both races that stopped my powermeter from working. In Athens, I had a front flat and the replacement wheel did not have a speed sensor. The speed data that I have for Athens is from my Garmin using the GPS. There was a lot of interference which led to speed spikes in the data. The power data is from my iBike, which won’t work without a speed sensor. Same thing happened in Roswell except this time it was my entire bike that no longer worked, and I had to switch to neutral bike. Luckily, I remembered to take my Garmin off and put it in my jersey pocket for the rest of the race so I could get heartrate and speed data – but no power data.

Barbers Ride to Live Race Reports


Wow, what a great day! This picture about says it all. My teammate Pat Allison won the Pro/1/2/3 race, and I managed to hold on for 3rd after putting in an attack on the last hill. Travis Sherman rode strong to finish 2nd after having won the Masters 30+ race earlier in the day.

Summary
Before I go into the details from the races, here is a quick summary. We fielded large teams for both the Masters 30+ race and the Pro/1/2/3 race. My teammate Wes Douglas made it into an early break with Joe Ruf from Madison and Travis Sherman (Marx and Bensdorf). Wes eventually took third with Travis taking the win. I attacked with two laps to go and then broke away from our chase group to take 4th.

For the Pro/1/2/3 race, we took 1st (Pat Allison), 3rd (Me), 6th (Terry Duran), 7th (Stuart Lamp), and 9th (Darryl Seelhorst). Pat and I bridged up to the winning break on the 2nd lap, and for a while we had five guys in the break. Eventually we finished with 3 guys in the break working our numbers perfectly to get the win!

The details – Masters 30+
For the Masters 30+ race, we lined up with six guys and were aggressive throughout the race. Wes made it into the day’s winning breakaway with Travis and Joe from Madison. Once their break was established, I decided to sit in and mark the strong guys to get the free ride across if they attacked. Unfortunately, there wasn’t much attacking so we lost our advantage in numbers as Wes was on his own to battle it out with Travis and Joe. With three laps to go, one of the Pacesetter Steel riders attacked hard, and I covered it. But the pack was still fresh enough to reel us back in. Then with two laps to go, I drifted to the back and then attacked into the headwind after the first turn. I bridged to another Pacesetter Steel rider who was already off the front bringing Will Hibberts (Alabama Masters) and Travis Werts (Sonic) with me. We worked together for a lap, but then I was feeling that our pace wasn’t fast enough so I attacked again on the last lap. Only Travis Werts was able to come with me and then came off on the last hill. So I rolled in for fourth. Sammy did well in the field sprint for 10th.

The details – Pro/1/2/3
We had eleven guys line up for the start of this race. I think that is the most riders we have ever had in one race! We raced this race pretty much to perfection as we were attacking and covering everything. I countered one of Stuart’s attacks at the end of the first lap and only managed to string out the field. Coming through the start/finish, there was a counter attack to my attack and we had 3 guys cover the move — Terry, Darryl, and Paul. Also in the break were Travis Werts, Travis Sherman, and Joe Ruf from Madison. The break was working well together and starting to establish itself. Meanwhile, back in the group we took turns covering moves.

Towards the end of the second lap, Ed Whitehorn (Velocity Pro Cycles) attacked and Pat covered it. They got a good gap right away and we were on the most difficult part of the course, so I decided to bridge across to it. I got away cleanly from the field and as I came up to Pat, I yelled “Let’s go!”. Pat thought the entire field was still there so I went flying right by. As soon as Pat realized that we had a good gap, he attacked the small group he was in and bridged back up to me. So the two of us were away. We caught up to the break into the strong headwind after turn 1. We came up fast and tried to rally the troops, but some of the guys in the break were already struggling when we tried to ramp up the pace. The end result was that we lost one of our own riders (Darryl) from the break and disrupted the rhythm of the break temporarily. It was a tricky situation because we did ramp the pace up quite a bit, which we definitely needed to do in order to get enough of a gap before the corkscrew downhill where the pack would make up some time on us if they were chasing hard.

Within half a lap, though, we had settled in and started a good rotation and had started to put some good time into the field. We continued at a blistering pace working well together all the way until just before the start of the last lap. Travis Sherman knew that we would begin attacking so he decided to jump the gun and put in his own attack possibly to see if he could reduce the odds against him. Pat led the charge and chased Travis down as the rest of us strung out behind. Travis attacked again before the corkscrew. Then coming into the headwind after the cork screw, my teammate Terry Duran put in a perfect attack because it forced Travis to chase. We caught Terry at the base of the final hill, so I put in a counter attack right away. I was pretty much dying by this point so I wasn’t going that much faster but it was enough to get a gap to force Travis to chase again with Pat sitting on his wheel. Coming down the finishing stretch, Travis closed the gap to me and came around, but Pat was waiting and came around easily taking the sprint by several bike lengths. My initial attack had given us enough of a gap that I was able to hold on for third with Travis Werts charging hard for fourth followed by Joe Ruf and Terry.

Kristine told me after the race that Tria was all over everything back in the field, covering every single move that tried to get away from the group. At the end of the race, Stuart attacked on the last hill and was able to stay away for 7th place with Jan Kolar just behind. Then Darryl won the field sprint for 9th. So that’s about it, what a great race!

Here are some videos from the Pro/1/2/3 race courtesy Kristine.

I ran out of battery on my iBike because I had left it running in between races and forgot my iPhone charger so for power data, I only have the first three laps of the Pro/1/2/3 race. I have annotated the attack as follows – 1) My initial attack 2) Waiting for Pat after he attacked to bridge back up to me 3) Finishing the bridge together to the group (400w min through here)

Which is tougher? Athens Twilight (USA Crits) or Sunny King (NRC)

Hmmm, just got asked this question by @Nashvillcyclist -


@nashvillcylist – an interesting question

The short answer is that Athens Twilight is the more difficult race because there are so many more variables that have to work out perfectly for a good finish (or even to finish at all). On the other hand, Sunny King is normally harder aerobically because there is no place to rest on the course. If you saw @AdamMyerson’s power data from the previous year’s Twilight race, (link below), you’ll notice that you get a “rest” every lap in Athens Twilight. This is not the case on the Sunny King course, you never really get a chance to rest on that course.

Adam Myerson’s power data for 2010 Athens Twilight

As far as numbers go, here is a side-by-side comparison of both races. I’ve posted my 2009 ride file as that is the only time I have finished. In 2008, I was in a wreck on about lap 60 that stopped the race. My rear derailleur cable was broken in the wreck, and the SRAM neutral bikes had already been given out. I lasted about three more laps in my 53×11 unable to shift and then crashed out for good on Lap #64 coming into turn #1 too hot so that I could try to carry my momentum up the hill on turn #2. I decided to call it a day. In 2009, I had a great race and made it into a late race breakaway very late in the race. When there was an attack from within our break (Heath Blackgrove), I was one of the riders who got caught out. Three riders stayed away with Heath taking the win. The rest of us in the break (maybe five of us) got caught by the field with about 5 laps to go. I finished 24th in the field sprint (27th for the race).

2009 Athens Twilight heartrate data – annotated

2011 Sunny King NRC Criterium heartrate data – annotated

The last statistic (number of laps) seals the deal for Athens Twilight as the more difficult race. To put it in perspective, the second lap of Athens Twilight is the most difficult lap of the entire race. The first lap bunches up and you are still full of adrenaline. By the second lap, everyone has separated enough for the race to be completely strung out single file through the start/finish line. You are absolutely crushing it as you fly through the start/finish line wondering if you can even hold onto the wheel in front of you. You look up and you see 78 on the lap card, which means you get to go around 78 more times before the finish. Ah yes, this is Athens Twilight.

Dothan Cityfest Criterium quick summary

Lots of strong teams and strong riders made the journey down to Dothan for this fun, fast, well-organized criterium. The race is part of Dothan Cityfest with tons to do for the kids (everything from pony rides to jump zones) and some great entertainment for the adults too. Our pro/1/2 race had about 50 riders, with many of those riders on one of several strong teams. Team Type I, Mountain Khakis, Aerocat, Global Bike, and Locos all had full squads. We fielded a team with three riders – me, Pat, and Stuart. There were several small teams like ours and then some really fast independent rider (e.g., David Guttenplan). Similar to last year, the race started out with attack after attack. I put in one of the first real attacks on the second lap and then covered a few more on the next laps. Then about 10 laps into the race, there was a slight lull in the pace as everyone was pretty tired from the early attacks. I saw a move materializing just after turn 1 on the hill, and went across to it. We had a six-man break that immediately got a few seconds on the field. I was hurting though from covering earlier moves and so after one pull I just decided to try to hang on. We were caught a couple laps later. At this point, I was toast and hoped that nothing would get away because I needed some serious recovery. Unfortunately, a move did get away a few laps later — a rather large move which eventually swelled to about 15 riders. I wasn’t going to just let the entire race get away, so every time the pace slowed down I went back to the front and just drilled it on the downhill. Fortunately, somebody would always attack through the start/finish so by the time we made it back to the top of the hill and our pace started to slow again, I would come around and hammer down the hill. This kept our pace high enough that we ended up pulling back the break after about 7 laps (judging from my heartrate data). Thankfully, this was close enough to the end of the race that it seemed the larger teams had resigned themselves to a field sprint and began to setup their leadout trains with 10 laps to go. I fought hard for position at the front, always moving up whenever I could, eventually finishing 12th in the field sprint. Ty Magner (Team Type I) crushed the sprint for the win with Thomas Brown and Luke Keough taking 2nd and 3rd for Mountain Khakis.

I’ll post the full report with pictures and videos sometime tomorrow evening. Heartrate data and new for this year, my lap split times based on the Strava GPS data … check it out!
