Hard work of late...

Getting into the swing of longer stuff as of late, completed a few 14 milers, a couple of 16s including one from our house to North Berwick, and then a 19 miler today which has kinda left me think if i'm really fit enough for a marathon....i've been having a lower hamstring niggle just behind my right knee for last few long ones but today, by about mile 14, the niggle sort of moved into full blown pain, especially on the slightest incline. I'll need to watch this one, it is fine this evening but I havn't ran since Tuesday so it has been well rested. In my favour, the route was a very pleasant rural one, over the back of the house to the Brunt/Woodhall, through Aikengall and into Oldhamstocks, down to Torness, along to Skateraw (ouch), then to Barn's Ness Lighthouse, Whitesands then up the hill homewards.
