6 laps of Austin 12 hour course
I started at the gun time for today’s race. It was interesting to have to start at a specific time rather than whenever I was ready.
I wanted to take a shot at pacing. I wanted to try to keep my heart rate from going above 145 and power under 200 watts. I thought I did pretty good with the heart rate, but the chart suggests I leaked over a fair bit.
My power was harder to see, but I tended to overrun on moderate climbs - in the 3-4%. My legs had no trouble pushing and they just over ran the target. I don’t have power on any of the bikes so that isn’t really viable as a metric to watch anyway.
This session really highlights a characteristic of the trainer that makes it less than an ideal simulation. Outside, I can coast downhill and get a good heart recovery. The trainer needs you to keep pedaling and just does some math to adjust your speed. I think the resulting pace is in the ballpark, but the mini recoveries don’t exist. I expect the difference would show as an average heart rate in the low to mid 130s, which I think is sustainable for 6 hours on hills.
I do think I should start out with relatively flat courses for these races again the clock. I also think I need to take a longer pause (5-15 minutes) at 120-150 minutes, and then at 90-120 minute intervals. Today I had a couple of pauses under 2 minutes: Just after starting when I noticed I wasn’t climbing yet - has started the wrong program At the end of the 3rd lap when the trainer software froze At the end of laps 4&5 to grab some calories
I have to decide soon if I’m going to try the Sebring 12 hour Feb 9. If it was closer, I would just give it a shot. I don’t really need a taper, but I might just do a couple of easy rides to scout the town part of the route ahead of time. I should probably plan an extra day in the hotel after the race in case my legs are shot.
I think I would be ok being the last person who didn’t DNF. I wouldn’t be surprised if the next to last had 20-50km on my distance.
