It was a very hot day, and due to leaving from home with public transport, I couldn't start till 08.45, so I ran in all the heat of the day. As it was unsupported I packed all gear, food and 3,25L (3L of water and a soda). Which gave me a heavy pack to start of with. During the run I only used public open water sources to refill and I really needed them. With temperatures rising to about 26°.
Untill 65km all went smooth and average was above 10k/h, but at that time the heat took its tol and speed dropped dramatically. In the last 10k I refound some speed, but the tarmac in Maastricht was burning hot.
Between the 3 countriespoint and Valkenburg there were some problems with the GPX. I ended up bushwacking, hit a dead-end and some minor problems. I took the GPX from the FKT site, but I recommend google for the latest version. I reckon this cost me about 10m, but it gave me some adventure.
