My first week of training I did 12.5 miles on Tuesday, 5 miles on Thursday and 19 miles yesterday. I am following the training programme suggested by the charity. My brother and sister-in-law supported me yesterday - I had my brother cyling behind me shouting "pedal faster, pedal faster" - he was telling me I was only cycling at 8 miles per hour and needed to increase my speed. Great support - I wouldn't have achieved the distance in the time without them both. It did not help that the bike I have loaned needs a service so I couldn't change down to the lowest gear. My legs felt ok at the end of the ride but I was physically worn out - I went to bed for an hour! I am wondering if I will be able to do the 52 miles in September.
