Last Thursday I signed up for the sundown marathon to be held on 26th May which is just about 1 months time away. This is my first marathon and I have only done previously 2 half AHM marathons in 2010 (1 hr 43) and 2011 (1 hr 53 min). I run 5 to 6 times a week each time doing quite comfortably about 10 to 14 km and the total for a week is about 60 to 70 km or so. The furthest I have run is in march this year which I went about 27 km in 2 hr 10 mins. Do I need to do more long distance runs lik
