After 6 weeks of intensive scientific research (!) here are my conclusions so far:
1. Ten seconds in to W1R1 you will suddenly realise you are no longer a teenager.
2. On a circular route, for every uphill there must be a corresponding downhill - except where you live.
3. After the euphoria of completing the dreaded W5R3, week six will kill you.
4. Whatever route you choose and whatever run you are doing, when Laura says "60 seconds to go" you will always be at the base of the north face of the Eiger.
5. The little gremlins inside your MP3 player are watching your elegant (ahem!) running style carefully. They are there to make sure that the image-boosting words "You make me go red....You make me sweat" are playing in your ear just as a group of slim, unruffled 20-somethings sprint past you with not a hair out of place.
Happy running everyone...whatever your age!
