Cool, I saw that one. Which bike?
I'll take the Greenspeed this time to see how alert I am by midnight. If I feel good when I am done I'll try the Bacchetta another time - maybe at the recumbent specific event in the fall. I'd probably go 15-20km further with it.
Can you switch between Greenspeed and Bachetta in the same event?
I probably could. I didn't ask when I confirmed they would allow the trike. If I like how it goes I'll check, but it would kind of be like me being my own relay team.
If I was switching, I would probably ride the Bacchetta until the sun went down and then switch to the trike. I'm really happy with the trike lighting system and with how it would react to any creatures finding their way onto the track.
I have no idea what kind of night lighting the track itself has, but I suspect not much outside of the put area.
I think I'll write out my plan so I can believe I have one and stop (ok, reduce) over analyzing it.
Seed myself towards the back to start and let the fast people sort themselves out while I take two warmup laps to learn the track. That might be less important when I'm not at motorcycle speed, but it worked well to pick turning points and where I could accelerate with a motor. Also, I don't want to burn energy in a regular warmup for a ride this long.
Then I'll target an average heart rate in the low 140s. I'll assess how high I want to push my max heart rate on climbs for the first hour, but will initially try to contain it to the low 160s. Based on my Ride to Conquer Cancer and last year's Tour de Pierre, I'm confident this will be sustainable, though I do have to be prepared for a different profile starting a 6pm rather than early in the morning.
I may adjust my peak for hours 2-4, but will plan to manage the average heart rate about the same, maybe letting it drift up to 145. If I feel strong and alert, I'll let the average go up in hour 5, but probably not above 150. For hour 6, if I feel I have the energy at 11pm to midnight, I'll let the max heart rate run up a bit more.
When I think I'm on my last two laps, I'm going to try to push the pace and see if I can build up to a hot lap to finish.
I think a Garmin longest ride is in range - this is about 20km less than the furthest I've ridden in a single day. A new day max (in my Garmin era) is probably a bit out of range given the elevation I expect.
