Pre-Race:
The concept of the Teuflischer Biber Ultra is quite simple: run 6 loops of 60k each in 10h each while collecting pages matching your bib number of all hidden books along the way to prove you found and passed them all. This year’s start corridor was described as „between 2100 Friday evening to 0600 Saturday morning“. 4 runners were brave enough to start the TBU 2025. During the briefing at 1900 we received the .gpx file, the printed map including the 18 dots for this year’s books and the description for each book. Similar to last year I plotted those 18 points as waypoints into the .gpx file in GC trying to be as precise as possible copying from a rather blurry printed map. After the last preparation were done the runner tried to find some rest. It was possible to lay down and close our eyes for some interrupted sleep waiting for the signal to start the race. The signal finally came at 0213 giving us exact one more hour to get ready to start.
Loop 1:
At 0313 we were finally allowed to start. The first climb to Book 1 gave a vague idea that this year’s edition could be a spicy one. Teun, Helge and me teamed up during the first climb onto Book 1 and sticked together for a little while longer. It somehow made sense to work together to find the books in the dark Eifel. With 6 eyes we were surprisingly fast in finding the first 8 books. Although the running speed of Teun and Helge was a bit above my comfort zone I tried to stick with them – an extremely important decision as it turned out I would need every saved second later on in loop 1. We split at Book 8 by coincidence – Teun ran the downhill way too fast for me and while trying to follow him I lost contact with Helge. For the rest of loop 1 I focused on pushing as hard as I dared with the fact in mind that there were more loops to come.With one eye on the timing I realized on the last 15k that there was no other choice than to go all-in in trying to get loop 1 done within time. Teun and I met once more at Book 10 which gave Teun a bit of a headache – together we found it and he could continue taking the lead. As the track was not only longer but also harder and equipped with more books compared to the 2024 edition I needed to fight for every minute at the end of loop 1. Finishing loop 1 I met Teun only 300 m before the HQ. He had his break and was starting loop 2 roughly 20 minutes ahead of me – something was definitely wrong at that moment – Teun should have been more than an hour ahead of me with his goal to finish all 6 loops.
Loop 2:
After 3 minutes refill and receiving the new bib number I started loop 2 with only 7 minutes spare to the 10h cut-off. It was crystal clear to me that I would not have the slightest chance to finish loop 2 in time – but so what: I was allowed to continue so why not at least try to relax a bit and collect a few more pages in the beautiful Eifel? Later in loop 2 I called the RD to pick me up – the fun was gone and to continue a journey I knew was a DNF seemed stupid. Even more surprising was that Teun also did not manage to finish loop 2 in time. This years TBU ended after two loops.
The TBU 2025 provided a beautiful course, wonderful books combined with perfect weather conditions. I finally had some time to discuss running and life with Teun – thanks for that, that is probably the best part of ultra: connecting to like-minded people and discuss one of the things we really love. Normally there would be hours between Teun and me running but this time we shared some time on the trail together – thanks mate, that was great and apart from the difference in running abilities we can work together quite nicely. Hope we get some more chances to do so.
After a short and cold night of sleep (which should have been a night out on the trails) we had the first coffee together wondering what happed and why we were already sitting there. We had several theories of why it went the way it did – later at home with a proper look at the data we found those theories to be true. We returned to the TBU with the impressions of the TBU in 2024. The track back in 2024 was a bit shorter than 60k – in fact it was only around 55k as the data show from both our watches. The 2025 track was around 63k. So we had to run 8k more compared to last year. Combined with a more technical track and a decent plus in D+ and 3 more books it finally made sense. The 2025 edition was way harder compared to 2024. Although it is of course the decision of the RD to create whatever he wants – this was too much of a change. It does not matter too much for myself as my abilities will never last for the complete distance but I feel really sorry for Teun. He prepared himself specifically for this event with the aim of finishing it off – only to be confronted with a 1.5h longer track. With this dramatic change it may not make sense to consider a third try at this race. At least the distance should be kept somewhat constant to attract runners for more than one try and give them at least a theoretical chance to finish. There are enough other variables (number of books, track design, D+) to provide something new and spicy every year. I truly believe the format is a great opportunity to provide something interesting to the BENELUXGER running community but only if it is kept in a reasonable and constant frame. The tendency to glorify certain events over there in the US is a mistake in my opinion and is not really helpful for the race future. It should be hard – it should seem impossible to most but it should provide a chance to finish so that the best can’t resist and can’t wait to line-up and give it a shot.
Nevertheless – thanks to the whole TBU team, the runners and supporters for another nice weekend!
