For a TT/RR I personally like to warm up on the roads around. Ive even done loops around a parking lot. Others prefer a trainer, but is not much of an option when you travel. I rarely see rollers at a TT warm up, but see lots of trainers.
Im looking to travel for racing a bit more this summer, particularly track, so interested in hear what people do since warming up for track has less options. Im one of those people that has no problem asking to use someone's rollers though (or not asking
)
