Hmmmm, so much for getting a friend to follow. Unless I just call someone who's already finished. It would royally suck to ride the 400 only to get disqualified.
I'm still on the fence. There's a guy doing it who's the same pace, but I don't know him well except for leap-frogging a bit on the 300k. If I slow down, I'm not sure he would wait for me.
It's not the distance that's the problem - I just did 344 miles at Sebring, but it was on a closed course - no cars at night, support always 1 mile away (racetrack loops all night long.) Although the elevation on this one is a challenge, I think I can do it.
I would send text messages when I could, and keep my cell phone handy. Or just do a gorgeous century with tons of people.
For 3 days, I get to part of a thousand other journeys.
