So far, the programme hasn't been that difficult for me. I pushed myself to get to the end each time I was introduced to a longer running period (3mins, 5mins, 8mins) but quickly adjusted to it. I just looked at the programme, and in just a few hours I am due to be running for 20mins straight. I could hardly make it through 8mins, it took real effort and lots of positive thoughts so I don't know how I'm going to endure 20mins. Please help!
