This is me finishing a marathon in 2014 - yes 26.2 miles jogging and walking in 6 hrs 34 minutes. I lost weight in 2013 using the 12 week plan then started c25k in January 2014. A 'friend' for my 59th birthday at the end of January 2014 entered me for a marathon in August that year.
My current challenge is 'swimming the channel' ie 22 miles, by the end of March in the pool raising money for 2 local charities. I am trying to persuade my friend, who is doing the challenge with me, that we ought to do at least a small part of it in the sea - we both have wet suits.
