My esteemed brother has set himself a challenge. He has decided to run a 10k race. I have both admiration for him and a suspicion that he's a nutter.
Now it's all very well to get into the old training routine and be going out for your run three times a week and all that. But even the most unlikely runners (yours truly) can find it does turn into a bit of an obsession. I speak from experience. I've got over my running obsession though, and have returned to levels of fitness that would require a time allowance of about 2.5 hours to see me complete 10k. Oh, and an A&E unit at the finish line to administer oxygen and rehydrate me and provide any other emergency care I'd almost certainly need!
You have been warned, esteemed brother, you might well get bitten by the running bug. I'd offer to come and train with you next month but I'll certainly slow you down. People can walk faster than I run.
