Andrew Craig, 43, from Caernarfon, has made 32 treks to the summit of Snowdon so far this year. They include two on one day after bad weather forced him to turn back. He is undertaking the challenge to raise money for the Breast Cancer Campaign and has already raised nearly £5000 - more than five times his original target - and is set to raise the target again this weekend to £7500.
"I'm hoping that I'll have to change that again before the end of the year," he said. By way of a change, Andrew will run up Snowdon this weekend taking part in the Snowdon race for the first time.
During the past six months Andrew has braved deep snow, sheets of ice and howling winds but he has only failed to reach the summit once.
