Who does it and what is the benefit? Curious that's all. Plus, I think its an interesting topic for discussion. Since some of the folks on the team work like mad to improve, stay strong, etc. it might be interesting to hear the rationale behind your training methods. Please someone reveal, unless, of course, these matters are top secret.
On a personal note I went running with some cats on the Glover Archibald trail this eve. Soon we will have to start wearing headlamps out there as it was getting dark by the end of the run. We hammered as there was some national class Italian Steeple Chase guy along for the ride who just killed us.
Legs are now jello.
