Has American ex-athlete Gwen Jorgensen He has shared with his followers on social networks a training series in height.
The session consists of doing 4 repetitions of 1 mile (1,6 km, 4 laps) each series faster than the previous one, with recovery at rest. Then continue with another part of speed training with shorter series.
This is the training, with the times I have done, that can serve as a reference for you to do the training.
Keep in mind that you have to do a warm-up at the beginning and a cool down after the session
