A 100 mile time trial? Wow, we don't do time trials like that here. Do you stay in your aero position the whole way? I think I would die - I'm impressed I don't even like 40 mile time trials!

You will do great no matter who supports you. I'm always glad of some kind of support. I've always done mountain bike races and would support (hand water to my husband); but always did them on my own with my own water (camelback or water sitting in the feed zone waiting for me) ( hubby just isn't very good at sitting around waiting).

So, if someone was willing to support me, I'd accept the help with a BIG THANK YOU!

BUt, you should probably do the race with support that makes you the most comfortable.
