Still wanting to build my running distance to 10k. I try to do an interval run and one slightly longer run each week. This week I incorporated a big hill that I thought I wouldn't be able to do as I usually run on flat railway tracks.halfway up I thought 'is this a good idea' but carried on slowly and made it to the top. I was really chuffed with myself.
What technique do others use for hills and are they important in building stamina?
