Whats your key training session?

We all have a training session we love or hate, a session that lets us know that we are in good shape or just a session that makes you feel like you have trained well.

We want to hear from you, tell us you key session and we will post one every week for people to have a go at. It can be running based indoor or outside or maybe a different session possible swimming or cycling.

For this week then, here is a session that is important for anyone doing a half or full marathon. The aim is to teach you about judging your pace.
The session is 2 x 4 min / 2 x 3 min / 2 x 2 min / 1 x 1 min

The aim is to run for 4 minutes then stop recovery is 1 minute and then run back the way you have just come from. The aim is to get back to you original start position, this will let you
know if you went too hard or too easy. It is best done outside possible around a park.

Have a go and let us know how you get on.
