Scafell Pike in under 2 hours, pretty good, mind you from Wasdale Head I used to be up and down in 2.5 hours in my running days, and when leading a group of 10 on the national 3 peaks, we were up and down in the dark in just under 3 hours.
The C2C however shouldn't be a problem so long as you don't try and go at that speed, the majority usualy take 12 days over the route, I average 38 miles per day and get across in under 5 days, once under 4 days on a straighter line.
Of course things don't always go to plan no matter how well you prepare, my last two 5 day attempts ended just after Sunbiggin Tarn and Gunnerside respectively.
During one trip I met a couple of female nurses who had planned the trip some time before, done loads of walks, and then one had developed a bad ball of foot blister during the first day to Ennerdale Bridge and couldn't carry on. The other girl was upset, annoyed and desparing. They ended up spending a few days at her parents in Keswick before re-joining the route in Kirkby Stephen. Their walk already ruined and judging by how the girl with the blister was struggling again on the way to Keld, before I left them, I did wonder if she had to stop again and whether their friendship survived.
