Spring sprints

Speed work today! I wasn't too enthusiastic about it, because I'm not really training for anything right now. I had been planning to take the whole summer off of doing any sort of speed work, and just focus on endurance training (at a low heart rate); but I was listening to a podcast during my long run and the guest (I think it was Matt Fitzgerald, actually) made a really good point...

He said that if you're not used to doing speed work, it's best to just focus on building a base of endurance training during the off season. If you've been doing speed work, however, and then you stop for a while, you'll be more likely to get injured when you resume speed work because your muscles will have to adapt to that again.

That makes a lot of sense! Speed work increases risk of injury, especially when you first start doing it; so by doing a small amount of it even during the off season, you are reducing your risk of injury when you start training hard again.
