Just got back from cycling the CTC (sea to sea) cycle tour. 140 miles from Whitehaven to Tynemouth through the Lake District and over the Pennines. Did it in four days, which I think was pretty good considering we were on hybrids and carrying our luggage in panniers.
Managed to do my knee in on a steep climb on day 1, so day 2 was uncomfortable, day 3 involved lots of pushing my bike uphill, and day 4 (the easiest supposedly), sheer agony trying to power through the pins and needles in the knee. Wifey was smarter in doing more walking on day 1 and raced past me on day 3 and 4.
Made it though. Need to start thinking about the next challenge
