Right at the start of the Dragons Back, 'Ruddles Rules' were very strictly imposed. Everything uphill (however slight an incline) was walked. Bearing in mind we were all going way beyond anything we had ever done before, and training was not exactly full on - more what we could fit in.

Ruddles Rules worked really well, mixing the walking/running seemed to help alleviate leg stiffness and problems after long days out on our feet. I would recommend it, due to injury much of my training was walking (hard, power walking including hills). Gained strength and time on my feet without the pounding.
