I just try to follow the program prescribed by my app, Polar Flow. I also used the Endomondo training program last year, it was cool, but my free 1 year subscription is soo expiring....so I just went with the softward that came with my running watch.

I haven't been on the bike regularly since baby #2 came along and now they're both in daycare at my job. Commuting by bike just isn't a viable option anymore, hence taking up running again. I prefer biking though. Oldest goes to kindergarten in the fall, so I may be able to get back on the bike again by winter 2018.

What kinda gear you have for biking? This was always a good time of year for riding for me (except when there's ice and snow).
