Sometimes you know that you have a very busy time ahead of you, and that you're going to have less time for fitness activities, for whatever reason (work, a new child, etc).
My questions is this- what is the least that I can safely run without risking injury?
Specifically, while training for a 10k/ half marathon this season I run about three times a week:
- an intervals workout (2 km easy, 1 km fast, 500*2 very fast, 1 km fast, 2 km easy)
- a medium run, 10-14 km
- a long, slower run, 15-19 km
If I want to maintain my conditioning with relatively little deterioration, can I run just once a week, my long run? (because I enjoy the long, slow run most)
How many days gap in between such a run can I have before it becomes "too much" and it's better to add another (possibly shorter) run in between?
