This Run Faster bundle gives you options. If you want to increase your run speed you can start with Run Faster 1, and when you have nailed a maximum effort session or feel ready for it you can move up to Run Faster 2 and 3.

As you progress through the series you get more fast intervals, and the fast intervals get longer.  4 minutes is the longest interval on Run Faster 1, that is 25% longer on Run Faster 2, and 50% longer on Run Faster 3.

Each session finishes with 30 second 'strides' or sprints for you to really stretch out your legs and run fast with Chrissie's encouragement. Two strides in Run Faster 1, four strides in Run Faster 3.
