I can just about run 5k now, having done my own adapted version, but I'm so slow. Today 5k took 40 minutes, but I was almost the same speed on the Kms where I was walking for a couple of hundred meters as for the ones I was running all of. I run on my own as I don't know anyone to run with. I also go to the gym twice a week and have some sessions with a personal trainer where I'm improving my fitness levels. Some weeks he makes me run very fast for 400m as part of a circuit. I'm just not sure how to get faster on longer runs
