I'm in the second half of my training to run my next marathon . I have been following the program set out in Runner's World endorsed book, Run Less Run Faster . The premise is that you have three "key run workouts" per week with cross training between workouts. I like the variety, and the cross training fits into my riding routines. The running program is basically speed work, a tempo run, and a long run. The authors have prescribed speeds and distances according to your desired finish time. I have done most of my speed work on the treadmill, which makes me keep the speeds I have set for myself, and I found the tempo runs enjoyable on my usual training trails near the house. Long runs are long runs no matter how you go about them. I recommend it if you are training for a marathon. I'll let you know how I do after the run. I continue to ride with the Legacy Cyclists as part of my need for speed and group activities -and cross training. We had 18 on Saturday...
