This weekend just gone I ran (well ran the first 18 miles) of the Boston Marathon, then cramp kicked in and the remaining 8.2 miles were agony! I am fairly certain the problem was the pace I set off at covering the first 13 miles in just under 1 hour 35 mins (my half marathon best to date is 1:34:54) how many times have I read advice from others and also preached to my kids during their park runs, ‘keep it slow and maintain your pace all the way round’. Well we all live and learn and hopefully won’t make such a painful mistake next time!
