Hi everyone. Here I am, oldish,( 54) fattish ( BMI over 25) , dodgy knee, loathe exercise but have lurked around this forum for ages, and have been persuaded by the enthusiasm and commitment of other posters. So, now on W1R3, sheepishly trying not to catch my neighbours in the eye as I puff past, redfaced and panting. One of them called 'Have you lost your dog?' as I ran past her house for the third time, wearing my dogwalking trousers as running trews. So, here I go. Feel like an idiot but will give it a try.
