Subject: RE: Bike trainer vs biking outside Like you, I have done almost all of my riding on the trainer since I broke my collarbone in a crash a year and a half ago. For a little while after the crash I was spooked about riding outside in traffic, but by the time I got over that I had come to really appreciate the efficiency and the controlled environment of trainer rides. I think that this has been almost entirely positive for my bike fitness. I ride consistently year-round, and the trainer is unforgiving in telling me how hard I'm riding. The only caveats to that would be: (i) Handling skills. Not a worry on the roadie, as I'm plenty experienced with that, but I do find that I need extra time outside with the tri bike, which comes much less naturally to me. (ii) Long rides. I'm a wimp when it comes to going longer than ~2.5 hours on the trainer. So I think for an IM I'd need more outdoor riding. (But I did ride a century this fall based on 100% indoor rides.) (iii) Core etc. I find that outdoor riding works my core, back, neck, etc. in ways that the trainer does not, so I get sore when riding outside in ways that I do not inside. |
