Is there any detriment to doing short intervals during base training this time of year?
Friel and Carmichael both suggest that VO2-type training should be deferred until later in the cycle, after maybe 8 - 12 weeks of base are laid down. But if you start doing shorter 60s to 90s intervals, maybe once or twice a week, does it somehow interfere with building an aerobic base? Put aside the issue of whether it increases injury risk.
During this time of year, work time and darkness conspire against me such that I only see daylight on weekends. So that means a lot of time on the trainer. Intervals are a way to make that time go faster, and have a big payoff for time spent.
Just wondering if there are times when you should not be doing them.
