warm up without bike Next weekend I'll participate in a relay triathlon (1100 mts. swim, 7 kms. run and 13 kms. MTB). I'll be doing the bike section, which is the last. Bike needs to be at the boxes area an hour before the start of the race. I guess I'll start riding about 40 minutes from the start of the race. That's around 100+ minutes since I leave the bike at the box. What can I do to warm up during this time or to start at full power without needing to warm up? I thought about riding a few kms. before parking the bike at the boxes, would it be effective after such a long break?

Thanks in advance!
If possible, borrow a second bike, and perhaps a trainer. There is very little that you can do to effectively warm up in a cycling effective way, other than ride. A light jog, and some stretching is the second best option.

It is a short enough ride for that to suffice, if it is your best available option.
