Charlie says, “Running on surfaces like ice, snow and mud requires different techniques to dry running:
■ Ice needs very quick and light footwork, almost as if you are running on air. The longer your foot stays in contact with the ice, the more chance there is of slipping. Your body should be as tension free as possible, but ready to readjust, should you slip. Of course running spikes will stop all or massively reduce the possibility of sliding.
■ Snow can be quite easy to run on and, depending on the type of snow cover on the ground, can be a real joy. Of course, snow comes in many different forms, especially in the UK. You can run down a slope with good cold, squeaky, hard packed (run as you normally would, but with more pronounced heel strikes), into breakable crust (high quick steps like running through high bracken) and the spring-type corn or granular snow and slush (hard in with the heels to create some form of traction). Each requires a different technique.
■ Mud is similar to both of the above, meaning very quick changes in footwork are required. In descent, you will find you can have a firm footing while the next can be all over the place. The best way to deal with this is to be ready for anything. Good balancing skills are key.
■ Uphill on all surfaces requires short, well-placed steps. Look for the best, most solid and grippy ground and steadily work your way upwards. Most important: shoes! Make sure you have enough grip.”
