It was the Comic Relief charity event this year, I can't do the link but if you google 2013 5x50 you should get the website. Basically it was to commit to 50 days (31st March to 19th May) of exercise I.e. 5k everyday running, walking cycling or 30 mins of exercise. The nhs couch25k website had a 'team' of around 72 and covered over 20k miles during the period. It was great to see fitness improvements over the 50 days and certainly helps the discipline of keeping the exercise going. Personally, I managed a 5k walk during my lunch break and then ran in the evening/weekends and did other exercise as and when I had time and covered 400k in the 50 days. Others, especially those doing a lot of cycling covered even more.
The next one is same time-ish next year, 2014.
