I'm doing my first triathlon in 5 weeks time. So far I've only been cycling on my hybrid bike but plan on using DH's road bike for the triathlon. I know this should improve my time but will it be it be any harder/easier/the same in terms of exertion? I'd heard the gearings were different as well or maybe this varies from bike to bike anyway?
I could ask DH but he's quite blase about it in a blokey sort of way whereas I'm quite nervous about the tri and want to get everything sussed!
