Well, I’m in again!
I’m sure the TR team will be frightened that people like me do this if they glance at my account. After working up to the 100 from a couch-sitting non-cyclist I’ve lined up for the 200 three times, and finished once. If you want to know what riding 207 miles in 21 hours is like for a ±215 watt FTP Type 1 Diabetic finishing DFL, just ask. I’ve had plenty of time to see what happens out there.
Tip #1: Most of the flats occur when people bomb downhill into the washes between rollers. That’s where the sharp rocks gather. If you’re going to be light & float anywhere, let it be there. Standard road bottle cages will eject bottles at those spots. If you see bottles lining the sides of the road, lighten up & watch your lines to save your tires.
Tip #2: If there’s any mud, the majority of mechanicals will come from the pointy end near the start. People amped up in a paceline will barrel into the mud, try to pedal through it, and end up littered roadside with broken derailleurs. Watch the low-lying areas when you first leave town. Being broken by mile 5 sucks.
