I do a 3-4 mile tempo once a week. I did this during my base mileage and have been continuing to do so since it's early in the season. My coach wants me to stop though. She says it was only necessary to do during base and not to keep doing them now. Is she wrong? If so, how late into the season should I keep doing my weekly tempos?
Which event are you focusing on?
You stop doing tempos the same week you stop running competitively.
Listen to your coach. For others with out a coach, keep doing tempos.
For 800-1500 runners I would transition with the tempos. If you have been doing 20 min tempos I would cut them down to 12 min tempos and add another element. Hills work great with tempos. 12 min Tempo, 10 min jog, 6 x 30 second hill sprint, 10 min jog, 3 x 200 at 800 pace.
3200 runners full tempo,10 min jog,4x 30 second hills. 5x200 at 1500 pace
