I am a 400/800m runner.
During winter I have been training like a 800m runner and doing 50 minutes long runs on my recovery days, but now I consider replace some of them with extensive tempo.
I was thinking of something like this:
10 min warm up. 10 minutes easy plyometric jumps. 20 minutes of relaxed strides across soccerfield (20 sec) jog rest (30-40 sek). 10 minutes of general strength. push ups, sit ups, back.
I believe this will keep my stride fresh for 400m and not make me loose speed as much as long slow tempo runs. And I guess I will not loose that much endurance if I keep 1 long run during the week of 1-1,5 hour. And of course I think this training is more fun than running slow for 1 hour.
will this be a good idea? any thoughts?
