What a disaster! Finally decided I had enough of back tracking on my route to fit the runs in so extended my route today. Wish I hadn't bothered! 1st 20 mins was great and I was feeling good, until I realised that small hills with flat and down hills meant I faced one huge up hill pull for my last 10 mins. It was like hitting a brick wall and I just couldn't do it So my 30 run became a 20 min with 10 min walk followed by 10 mins running because I refused to give in. Will be reviewing my route for me next run!
