It is an absolute privilege to be able to participate in this event!!! The scenery is stunning and it has to be the most beautiful of any race. Plus it is well organized with plenty of aid and well supported by spectactors and fellow runners.

The first 16 miles are rolling hills on a combination of trails and paved roads. You can push yourself during this stretch since the steep inclines during the last 10 miles require a lot of walking with a few runnable stretches. The last 4k is surprisingly congested single file climbing with minimal chances for passing. But the view of the Jungfrau at this point can be truly appreciated during the slow pace (take a camera!). The race has a 6:30 time limit, but it is the 5:30 cutoff time at the 38K that is strictly enforced. The congested climbing for 3K with a 1K decent to the finish, can take an hour. As a regular 4:30 road marathoner from Ohio (with no mountains to train on) I passed the 38K at 5:10 and finished in 6:10.

There is plenty of food and beverages available for purchase at the finish area. Hot showers and drop bags are also nice at the finish before the train ride down. Be prepared for a long congested train ride full of friendly spectators and finishers. The train service to the start and from the finish makes it convenient to stay in some of the beautiful, quieter surrounding villages of Interlaken (Wengen, Lauterbrunnen, Wilderswil).

As someone who has completed over 70 marathons in beautiful places, I can not say enough good things about this event and the beauty of the scenery. It helped that the 2012 race had perfectly clear conditions. It is hard to get into this race but if you get the opportunity you will not be dissapointed.

I did my 50th marathon in my 50th year and eight years down the line I was persuaded to join a couple of lads from my club to have a go at the Jungfrau. Apart from my 50 marathons I have cycled a bit , Time Trials up to 100 miles and sportives of over 100 miles. Also as we speak I am European Duathlon age group champion but last week tops the lot, the cammaradarie, the pain, the euphoria, the emotion,I have never known an experience like it. I ran wearing a Scottish vest and to have a piper play Flower of Scotland for me at the highest point was somthing else. Full marks to the organisers too, faultless. A fantastic event which in my opinion warrants the title 'The Ultimate Marathon Challenge.'

This was my second running of the Jungfrau Marathon, having run it once in 2009. You can expect to run the first 16 miles of this marathon before hitting the first serious incline. At that point, unless you have amazing lungs and quads, you will be walking for a bit. Just when you think you will be walking for the next 10 miles, you will hit a stretch where you can run again. That is how the final 10 miles of this marathon play out, and that's the reason you will see the distance markers broken down into quarter-kilometers during this phase of the race. Don't despair, though; the scenery surrounding you will almost certainly take away any pain. You cannot stop staring at the snowcapped mountains as you draw closer to the Jungfrau. If you want a good estimate of how long this marathon will take you to run, just add about 1 hour and 45 minutes to your road marathon time. If you are not running a sub-four hour marathon, you really should not be attempting the Jungfrau. There is a cutoff time of 6 hours 30 minutes and it is enforced.

Along the course, you will have plenty of water/fuel stops as well as cheering spectators. The only complaints I have is that at the pasta party you only get one plate of pasta and a banana. A second plate really would be appreciated along with some salad. My other complaint is that at the finish, they hand you a bottle of a sports drink, but no water is available right away. It is a fairly long way from the finish area to the refreshment area so some water early on would have been welcome. This year, I put two liters of water in my bag knowing that getting water after finishing would be an issue. Finally, be prepared for a very crowded train ride down the mountain once you are ready to leave.

Organized with the precision of a Swiss clock, with wonderful support through the villages and extremely helpful water/food/aid stations. Starting in Interlaken you get glimpses of the distant mountains, then through the progressive climb these get closer and closer. After the final climb, it's downhill to the finish under the Eiger/Monch/Jungfrau range is spectacular and spiritually elevating. I felt that I had really earned both the view and the T-shirt. My first mountain marathon, and I'm still buzzing. The only problem is to find something as exhilarating to follow this.

Fantastic from start to finish. I'd been injured most of the summer but the views and crowd spurred me on. Not a great time, but who's looking at the clock in an environment like this? Will be returning in 2011.

The Jungfrau Marathon is astounding! The most beautiful event I've ever done, and organized to perfection.

Do yourself a favor and be in good shape for this one. The first 10K are flat, the next 10K contain gradual climbs and then... it gets TOUGH as you go up the mountain. This is sort of a hybrid event because it gets so steep in many parts that you can't run. But it's so worth it!!

This one is for people looking for a unique challenge in a spectacular place.

What a fantastic race! This is a marathon that everyone should do at least once in their life. It is a major challenge with lots of power walking up the hills. The course is very crowded throughout the run, so try to seed yourself correctly at the start. Otherwise just enjoy the race and pace yourself. Weather this year was overcast by noon, so you could not see very far once you were going up the mountain (it may have been a good thing). The finisher's shirt and medal are worth the effort (if you finish the entire course).

Everything is perfectly organized. The scenery is amazing throughout the entire course; there were times when I did not know whether to admire nature or keep on running. I ran 5 races before, but this was the first I did not finish (on time). After 30K, the organizers were basically chasing the last runners (including myself). Unfortunately I was stopped at 5:45, with 4K to go. I still believe I could have finished on time. Anyway, I got my medal and finisher shirt. Looking forward to running and finishing this spectacular race.

If you only ever do one more marathon then make it this one. It's a complete and utter privilege to be able to do such a run, so I'm doing it again this year (2008). Enter it as soon as possible (guaranteed entries still available if you go on the training week or weekends). I did the training week last year and it was fantastic.

This is the only marathon I have ever done where I was not glad to see the finish; I was enjoying the experience so much I would have happily had it last a bit longer. The scenery is superb, the finish below the Eiger unforgettable, and there is great support, a great atmosphere, and top-notch organization. Covering the course within the 6.5-hour cut-off is not a foregone conclusion (particularly with the time needed to take all those photos) so be prepared (unlike me). My only negative thought about the event is that it could be a long, long slog in bad weather.
