Good Morning David
My name is also David by the way.
There is a motto start slow and finish strong ,going slower in the beginning and I know this is going to frustrate you but in the end it pays off dividends .For every 7 kilometers you run,walk for 2 minutes,then carry on running.So in other words for every 7 kilometers you walk 2 minutes and then carry on running and rehydrate yourself but don”t over drink at water stops as this can cause cramping .This means 7×5 equals 35 kilometers ;then run the rest and I promise you that you will finish strong.David I can assure you that if you do this you will finish stronger in the 2nd half of the race providing you do not outpace yourself.I also learnt the hard way starting to quickly and cramping 2nd half of the race which not worth it;having to walk the last 8 kilometers of the race cramping.A friend of mine suggested this and I was surprised .I saved myself 26 minutes and went from a time of 4:13 to 3:48.So just think walking 2 minutes x 5 equals 10 minutes can save you a lot of time when you see my times not boasting just making a point .Good luck
