After months of thinking about it and listen every week the the podcast (5 stars BTW) I’m pulling the trigger and signing up.
I ride both MTB and road, but my target events in 2020 are MTB. my B+ event is a 24 hour race in February and my A event is a weekly race series in the summer.
So my question is this. My road bike a Giant TCR is all set up on the triner and I use it often. Is running the MTB plans while on a road bike ok? Or should I mount a slick on my spare MTB wheels for the trainer? I’m looking at the Olympic MTB plan as my A race is short 5 mile loops.
Yes, that is fine. Especially in the beginning of the plans, you are building fitness as the main goal.
This might make more sense as you get closer to your event, with a goal of optimizing and getting more specific to your goal.
However, that would likely mean a bunch of back and forth loading and unloading the bike (and swapping a tire/wheel), which adds to the mess.
It is likely a small difference in general that is fine to ignore and try to do some workouts outside on the actual MTB, as you get closer to your event.
Riding on the trainer will build your pedaling fitness - cardio engine, muscular endurance. You can do this with a road bike on the trainer.
Riding outside on your MTB will build MTB conditioning and skills.
I don’t think there’s much to be gained from riding MTB on the trainer. Yeah, the positioning is different, but you’re so static on the trainer anyway, I don’t see how there’s much carry over to building strength for riding MTB outside.
I’ve trained for MTB Marathons the past 2 years, almost exclusively on my roadie on the trainer. I’ll mix in some outdoor road rides when it’s nice outside and then add some skills sessions on my MTB once a week. Not ideal but the races i’ve done aren’t that technical, where handling becomes crucial.
Although I planned to put my mountain bike on the trainer this past season while preparing for some long events like Leadville, I never did and stuck with a road bike on the trainer that I have dedicated for indoor work only. I still did a lot of long outdoor rides on the mountain bike, both on road and dirt, so didn’t feel I was missing much.
With the road bike, I made sure to set things up similarly especially in relation to saddle height/position. I also tended to ride on the tops of the bars, rather than down in the drops, while on the trainer. I have found in the past that small differences in saddle height can make me more susceptible to cramps when switching between bikes.
