So its still wet, cold, and miserable outside where I live and it's nearly impossible to get on the bike outside. I do have a spinner bike that I can use to simulate biking but it's really boring and I get way too hot and theres really just way too many problems with it. My winter training has basically been running at the indoor track near me and I've really improved my running skills but I'm wondering if this will help me at all with my biking.

When I started running after the summer, my endurance had improved dramatically due to my time on the bike in the summer. I'm hoping the results will be reciprocal and help out my cycling. If you all are wondering, I am doing interval training as well as a lot of work in zones 4 and 5 heart rate wise when I run. Any feedback is appreciated!
