August lashes out in volcanic fury

[Sweder]

Actually, it really doesn't matter. I've been through all this. Once you break the shackles it's plain sailing. What starts out as a gentle jog around a known circuit can translate into a PB, just so long as you don't care too much. Run for the love of it, for the thrill alone, and you will improve your state of mind and your physical endurance. Change your route mid-run. Cut a run short - go on, I dare you - simply so you can chuck in a hell-for-leather, eyeballs-out sprint where one WASN'T PLANNED. Liberating. Head out to Blackcap without knowing if you'll turn left along the Moyleman, right down the chalk pits or straight on to Ditchling - or even turn around and run home - until you get there.

Did you ever read the Boff Whalley book? Or Running Free by Richard Askwith?
These are the books you need now.
