So I'm coming off a couple injuries that has kept me from a lot of training this year and in particular off my tri bike for more than hour ride very often. I'm doing steelhead in 2 weeks and planning to drop out after the bike. Already paid for it and have the vacation scheduled to go back home and see family so at least want to do something.

Question is. What's faster? Just riding my road bike (2011 stock trek 1.2). Or I can ride my tri bike (2013 stock felt b16 w/disc cover) and spend a lot of time on the pursuits instead of in the aero position the whole time?

Also not 100% certain I'd make it through 56 miles on the tri bike depending how much time I stay in aero.
