I started and stopped at Broadway and Lee Hill.
Splits:
Audubon trailhead: 1:47:30
Transition #1: Under 2 minutes
Audubon summit: 2:49 and change (1 hour up)
Audubon trailhead: 3:26 (38 minutes for the descent)
Transition #2: Under 2 minutes
Broadway and Lee Hill: 4:10:20 (41 minutes or so)
Felt descent, but not great. The ride up seemed to take longer than I’d originally hoped, but that may have been because of a slight headwind that grew the further up the climb I got. My power on the bike was sub-par from lack of fitness, but also just a bit of fatigue for some reason or another.
My legs felt pretty dead for the whole run and I ended up hiking a lot of it. I stuck strictly to the trails, as that seems to be the rules for this event, and was pleased when I didn’t get lost (I’d never done Audubon before). I took the running decent fairly casually, not feeling like I had good coordination today to run fast downhill without taking a tumble.
I was happy to have a fast tailwind for the ride back down to Boulder, and didn't have to exert too much energy until the backside of Lee Hill, which went by quickly and without too much suffering since this the day ended up being a fairly short effort. Miraculously, I didn't get stuck behind a single car on the Lee Hill descent!
I brought two Garmins with me, though the bike Garmin got turned off in my pocket for half of the run. Power data for the bike portion:
Average power from Broadway to Audubon trailhead: 287
Average power back down to Broadway and Lee Hill: 175
Full run file and bike Garmin GPX file are attached.
