Just entered the ballot for a place in the 2015 Virgin London marathon.
I ran it in 2012 and was on for a 4 hour 45 min finish (as you may gather, I am no Mo Farah!) but injured my knee at mile 9 and could only manage to run for around 60 second bursts every 5 minutes or so. So limped home in a disappointing time 5 hours 53 minutes.
I didn't run for a few months after then when I did start again I lacked any real motivation and found it hard to run for more than one hour at a time. By the end of 2012 I stopped running for 6 months and only started again when I joined the gym last summer. I got myself fit again and was near enough back to fitness for 5KM runs then I lost motivation around Christmas time and as a result have ran just once since Christmas (a month ago) I also gave up my gym membership because of a dispute with them over what I was promised when I joined.
I have no intention to run any other marathon but enter the ballot every April for the London one as I have a point to prove to myself that I can do it in under 5 hours! I didn't get in in 2013 or 2014. So hoping this time around I will be successful in the ballot, only thing is they don't tell you until October!
