I cut my hand open on the descent from Scafell in the Borrowdale one year. The only way I could stop the bleeding was by gripping a palm sized stone. This got me down to Styhead where a Marshall had some tape which did a better job. I thought adrenalin wore off after a short while but I actually had my best ever second half run in that race. The carry on afterwards to get it repaired was a minor epic of logistics involving my bike, a friend's car, my campervan and a kayak - a bit like the old proverb about getting a fox a hen and a bag of grain across a river.
