Details: First time participating at the Jungfrau-Marathon. The goal was under 5 hours. I tried to not start too slow (I know usually it is the opposite 😊). Reason: I heard that it is almost impossible to overtake near the finish. Therefore I tried to have a good pace in the more flat part. My goals were 10km under 1h, 21km under 2h, 30km under 3h. The hardest part was after Lauterbrunnen. Although it was very flat, I felt my legs already a lot and slowed down a bit. Up to Mürren was okay again (it was anyway too steep to run). As soon as the nice mountain path started I could speed up and the nearer to the finish the better was my ranking. Finally I finished it with a time of 4:52h and was very happy with that time. The feeling when reaching the finish after such a distance is indescribable for some minutes until the legs start to ache again. The recovery of my knees also only took about 2-3 days (stairs were the worst 😄).
