In the last couple of weeks I have been running shorter distances, but more regularly, and have a question about whether this will affect fitness etc. Basically, I've still been running 35 miles a week, but going out 6 days rather than 4. So I haven't done any really long runs (longest ones being 7 or 8 miles, and doing a few 4 and 5 milers). Basically I just haven't had the motivation or time to do any long slow runs. My question is, if I have weeks like this, will it negatively affect my fitness and will I run the risk of putting on weight, or does it not matter as long as I'm still covering the same distance per week? Will longer runs become increasingly difficult if I adopt this new schedule for too long?
