Five to end the week:
1. The most difficult marathon in the world? Look at the elevation profile
2. Trail running etiquette when it comes to, err, Number 1 and Number 2
3. Nice profile of Amy Sproston
4. Pronation and running injuries
5. “i might run 180 miles a week” (ed. – DANG!)
Run safe this weekend, be wise in the heat and run by HR or perceived exertion.
