After a 50k, 6.5 hour trail run I guess I can call myself an ultra runner now! Because of all the rain in the days running up to the race the course was brutal. Some descents were so slippery I had to sit on my butt and glide down in order for me not to fall! Unfortunately my back was bothering me a lot during the last 20k. I think it locked up completely after the crash in Hamburg two weeks ago, and trail running definitely made it worse. I still had a lot of fun though. Surely something I will be doing again someday, but first another full distance triathlon! Challenge Almere-Amsterdam is already in less than 5 weeks.
