I managed a 5k PB today by taking 21 seconds off my previous PB. I am currently ranked number one in the lightweight rankings (although I am the only lightweight to have entered a time so its not quite justified!).
2011 5k = 23:17.5 = 2:19.7
2012 5k = 22:56.9 = 2:17.6
Let me know how you all get on with this classic row.
