Well a small hill near my house. There is a small trail near my house that I have take to running during the week. It starts with a mile on the road which is a nice warm up. Then there is a short sharp climb for a third of a mile. It’s pretty steep, it averages 11%, parts of it are nearly 40%. I have to walk some of it but those sections are getting smaller. This week I managed to push it and steal the Strava KOM.
