Started from Lassalyckan with 500ml hard mixed sportdrink (240g carbs) and 1 500ml water bottle with filter. After 17 km I got to Vegby, where I filled with water on the public tap at the camping café. After that, there was a stretch with bike paths around the lake, and than back on gravel roads. After 31k the route went steep down on a small trail, and followed the lakeside back to Ulricehamn. Here I started to feel all the flat running, and got really tired, and the pace slowed down on the technical trails by the lake. I filled the filter bottle with water at a small creek at km 35, and continued past Ulricehamn. At km 44 I started the last uphill towards Ulricehamn golfcourt, and took a gel and follow the marked trails back to the start. Should have brought a bit more energy perhaps.
