An unclimbed line caught his eye. After struggling to get up it on a top-rope, Colin realised it was likely to prove too hard for him to lead. So he got some younger and better climbers to top-rope it, giving him an idea of how far out of his reach it was. They reported back it felt around F6b+, was very worthwhile and urged Colin to continue with his efforts:
"So I did but one day with my wife Sue I had a mild heart attack on the bloody thing - I suffer from Angina - and called it a day for a while."
Neil Gresham later drew up a coaching programme for Colin which he followed to the letter for three weeks before going on to successfully lead the climb, partnered by Mark Helliwell.
