It’s funny- I remember Charlie mentioning that during training camps, instead of going nuts on speed work, they would take advantage of the grass and good weather and do a lot of tempo / recovery work. Your training camp sounds like a recipe for injury. Trying to cram things in because it’s a training camp can cause more problems than it solves.
Two-a-days can be a good idea, but it sounds like they went a little crazy with the speed work. How are you feeling now?
