Run Mileage for 2009

My monthly & weekly run mileage increased significantly in April 2009 compared to the months before. I think I am paying for the extra mileage in the discomfort I feel in my right knee and elsewhere around my 2 legs. :(

Sep 08: 13km
Oct 08: 44.72km
Nov 08 22.81km
Dec 08 10.00km (stopped after SCSM)

Jan 09 3.07km
Feb 09 28.30km
Mar 09 27.20km
Apr 09 61.29km

But still can't exceed the 15km mark and 14km is just 2/3 the distance of 21km half marathon. Less than 4 mths to countdown.........
