Very nice day today...temps in the low 40's...but with the deer hunt going on was forced to do the trainer. I rode 50 minutes of 1 x 3 intervals. We have not burned wood since 1982. This year we installed a new wood stove and that will be our main heat source this year. I discovered quickly in the beginning of winter, that wood heat and the trainer do not mix well. When we heated with the gas, it was turned down during the day while we were at work...so...when I got home from work, the first thing I would do is the trainer while it was still relatively cool. It could be a good thing as it may force me to do more winter riding.
