Has American ex-athlete Gwen Jorgensen He has shared a series of height training with his followers on social networks.
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 warm up at the beginning and return to calm after the session
