Since there was no Unsupported Fastest Known Time (FKT) declared for the black ExtraTrail route in Stoumont, I decided to give it a go today. My goal was to end below 3 hours, but that turned out wishful thinking: I was able to keep up the 3 hour pace until somewhere halfway, but then started slowing down due to fatigue and heat, resulting in a positive split of 21 minutes.
To save on weight, I only carried two 500 ml softflasks and a handful of powerbars and two gels with me in my trail backpack. Using my MSR TrailShot pocket-sized water filter, I refilled both my softflasks from a natural source after about 17,80 km. In total, I consumed 2 liters of water, 2 gels and probably 1 small powerbar.
A Big Thanks goes to my brother who took off some 3 hours ahead of me to walk the trail and take some pictures when I caught up with him :-)
