I caught a glimpse of a Chris Carmichael book which had a section on what the equivalent of spinning indoors on a trainer would be to real world riding outside.
I don’t remember which book it was, I quickly looked through it at a friends b-day party. Does anyone know of a web site to find this kind of info, or have an excel type chart that they could post. I think this would be helpful info come winter training time.
Awhile back, last fall maybe, Triathlete published an article on use of trainers, something like an hour on the trainer is equivalent to 1.5 hr’s on the road. I don’t recall who wrote it but that seems about right to me.
