I would say run how you feel, but always get a doctor's advice. My advice, to get your stamina up a wee bit, is to do 10 times 100 metres.Try to get round about the same time for each rep--don't burst the first one. About 60 per cent each rep. Recovery--half the rep time
Do that for 2 days a week, five days apart. I want to do a disclaimer so that I don't get pulled up by the powers that be.
I am not qualified to give any advice on fitness/running. If you are willing to participate, I will not be held responsible for any injuries or loss sustained as a result of this post. You participate one hundred per cent under your own authority, not mine.
Nuts, I know, but people are watching
All the best, it's a start Kevin.
