Here is another option for speed training: Farklet Runs.

You run 3 minutes at a fast pace, whatever that is for you, and then 1 minute at a recovering pace. And repeat X times.

The difference with stride repeats is that here you run slower for a longer time.

Start with X = 1 and increase weekly.

Search #speedtraining if you missed the description of stride repeats.
