Bike training in the snow

Right now I am training for IM Louisville and I have an easy hr and 15 min ride to complete tomorrow. The problem is Lexington is supposed to get a lot of snow, so riding on my road bike may not be an option. I am sick of spinning classes and riding my trainer. I want to get outside. Is it a bad idea if I take my mountain bike out tomorrow for a nice snowy ride?

I ride my mtn bike in the snow in Minneapolis all the time, I love it. you will go a lot slower, but you can still push yourself for a good workout. Just make sure you wear a helmet.

15 minute ride?

15 minute ride?
1:15. Most everybody gets tired of the trainer. That said, I’d ride the trainer.

My mistake, I read the hr as heart rate!
Even at 1:15 I’d still rock the trainer as well.
