2old - Good news on the run. Yeah sometimes it's harder arriving a few days early and then having to wait for the race. Did n't video it but it was funny to watch.
red - Hope its a speedy recovery for you , just say the one brown tight is a new training idea and everyone will be doing it.
Strange run for me this morning, just under 21 miles at just over 8's but a real struggle from 16, lack of energy even though I had 2 gels. Maybe still tired from yesterday's bike or last night's stir fry(not many carbs) was n't the right meal choice for a long run. Got home and felt out of it, some flat coke, peanut butter on toast, pancakes, some biscuits and a short nap and all good.
Martin - you say every mile was a struggle, so maybe it just was n't your day, there are so many factors that go into running a marathon. Don't lose hope of the sub 3,your HM time indicates a sub 3 full but it's not always a given as some have a better natural abililty at speed endurance. I have a 1:27 half but have never gone under 3:15, the marathon can be a difficult beast to master for some.
