The two Swiss Silvan Marfurt and Ralph Van Den Berg break through the “sound barrier”: In one day, they conquered 20,845 meters / 68,389 ft of vertical descent on the Davos Klosters single tracks. A new mountain biking record.

The rules: No trail can be ridden twice, and no e-bikes. This is what the two amateur mountain bikers Silvan Marfurt ( 1988 ) and Ralph Van Den Berg ( 1985 ) stuck to on Tuesday 20th July when they set a new world record. In 16 hours, the two conquered a descent of 20,845 vertical meters / 68,389 ft in Davos Klosters. Hardly surprising! The Swiss biking destination is known for its almost infinite number of single track trails and its Bahnentour, or “cable car tour,” which is what inspired this world record. “The Bahnentour, with its descent of about 10,000 vertical meters / 32,808 ft, is my favorite Davos Klosters tour. I rode it several times to prepare,” stated Ralph Van Den Berg.

Cutting it close
The two headed out at four a.m., marking the start of a non-stop ride where every descent was on a different trail. They were on a very tight schedule. After 16 hours of trail and cable car riding, their GPS device showed that they’d reached the desired descent of 20,845 vertical meters / 68,389 ft. They’d made it! They beat the official single track world record by 229 vertical meters / 751 ft.

Single track world records a Swiss tradition
The single track world record is a long-standing tradition and is held mostly by the Swiss. In 2010, Thomas Giger, together with René Wildhaber, set the first benchmark with a descent of 12,555 vertical meters / 41190 ft. He beat his own record three years later along with Thomas Frischknecht, descending 13,572 vertical meters / 44,527. Twins Caroline and Anita Gehrig beat the record in Vinschgau in 2014, descending 15,117 vertical meters / 49,596. One year later, Ken Imhasly and Alain Gwerder were the first to cross the 20,000 meters / 65,616 ft threshold in Wallis, until they ceded the title to Silvan Marfurt and Ralph Van Den Berg in Davos Klosters.

 Ah yes, ebikes are bad but gondolas good. Sounds like a day well spent though!

 Lol, there's some lines you just can't cross!

 nobody said they are.. but if there are sections of trail where power assistance is advantage then needs to be separate e bike WR category
  • 10 7
 @a-d-e: yeah the separate no-trail-twice, no-ebike, no left-handed, Japanese dentist category. WRs are so dumb nothing against LH Japanese dentists.
  • 4 1
 @gravity354: one thought same. Why put all these conditions on yourself and call it a WR? Surely just the longest lift with the qyickest turnaround and the highest VD would be a winner, regardless of ebikes, trail duplicity, handedness or nationality.

One would be interested to know which lift has the best numbers in this regard. Perhaps a combo of lifts. Which resort is the highest, which has the most VD, which one has the quickest route to the bottom?

I see this WR falling!

 Meh. Still more impressed by the guys who did the record back in 2013 on Mount Seven using the Redbull Psychosis trail. Sure a lot easier to break the record when you aren't hitting double black diamonds the whole time.
  • 4 2
 probably plenty of time for a spliff at the bottom of the double blacks tho bro

 Having ridden Mt 7 and the Davos area, I'd say it really depends on the trails. The one difference with the Davos area is exposure. Even some of the easier trails, if you mess up the consequences of going off trail can be high. Two pretty different but massive accomplishments. Props to anyone who goes out and does this type of stuff. On a side note, one has to pedal a fair distance between some of the lifts. The next time i go to Davos I'd like to try the the Davos 10,000. An easier task to do but still a full day.

 „After 16 hours of trail and cable car riding* - but thank god NO eBikes! LOL
  • 5 3
 They could have done even more with an e bike, especially a double crown e-steed.
  • 8 1
 Looking forward to the tech write up of the equipment used to be able to pull this off cuz that cable car looks gnarly!

 Remind me of an epic day heliboarding in Bella Coola when a buddy and I logged 47,000 vertical feet. First day out after 4 days of weather hold and after lunch all the skiers dropped out so the two of us and the guide had the heli to ourselves. It got so outrageous that we started straightlining rid, racing the heli to the pickup. A day for the ages…
  • 1 0
 i wondered initially if they had heli for this record. dont say if can inly access via open public transport to trails. wish was more detail in the write up

 I'm kinda skeptical that's the world record. How much vert were guys doing at the old 24 hour DH races at Keystone? Seems like it had to be more than 68k.
  • 2 0
 Yeah. I just did 32,900 today at the park with a big lunch break and an hour in the shop. 16 laps. I know guys here who get in 27-30 laps in a day. If you focus it seems like you should be able to do a lot more.
  • 9 7
 Oh, they gained unbelievable 47metres with muscle power - now THATS a record! Hope they were equipped with AXS1x12 10-50 and 28 teeth front max to achieve that Wink
  • 3 1
 there are descending sections of trail that ALSO require pedal power below 15mph.. its a WR effort so strict boundaries need to be set. its an achievement not only of descending elevation- if someone in mountains of chile can beat for example let them try. its a feat of knowledge and experience also.
  • 1 0
 Now this is a record I can get excited about. Although I struggle to get my head around it as the most elevation I lose on my trails is 180m.
  • 1 0
 must need to know the trails well to even consider this. bet whole route pre planned even knowing how long to get gondola trip to top.
  • 3 1
 So, what's the e-bike record?
  • 2 0
 Would be 3 times the elevation in half the time therefore allowing more time to be spent in the pub afterwards. (With spare batteries of course)

 @mcozzy: ebikes don't have the same range as analogue bikes, unless you have 3-4 spare batteries. If you want to do really big, really long days on a bike, get a good lightweight trail bike and carb load.
  • 3 3
 @Lokirides: just not true at all! I have a kenevo, a remedy and a spark and I can do the longest days by far on the kenevo.

Using blevo or mission control, and I'm sure bosch/shimano etc must have equivalent apps, you can change the amount of assist from the motor, blevo even has a smart power feature. For example, if I use blevo's smart power feature to set my kenevo to keep my power in zone 2 I can get over 100km. I regularly do this in the summer, and not flat rides either, proper rides with real climbs and descents. I can't do get close to that on the spark or remedy.

My favourite bike is my remedy, and I prefer non-ebikes for sure so spare the pitchforks, but there is so much BS out there about ebikes. If you want a harder workout or a longer range you can just turn the assist down.
  • 5 3
 @everythingscomingupmilhouse: I have an Enduro - do you think on your Kenevo you could do 44 miles and almost 9,000 feet (with one battery)? Or how about 73 miles with 10,000 feet (Pisgah 111)? Can an ebike do the entire Kokopelli trail in a day (I can't... but people do!)? With an ebike, you're limited by the battery, no matter how good the software is. With my Enduro or my Epic Evo, I'm only limited by fitness and how much food I can carry.

I know that someday ebike batteries will catch up with my legs, but for now, my legs have more life than lithium. This isn't me hating on ebikes, I think they're cool, but their range is limited, and you, my friend, are limitless =)
  • 4 4
 well nobody stopping anyone from setting an ebike record but ebikes aint mtbs so let them set/get own record. probably close but SEPARATE achievement. this is achievement of planning skill experience knowledge fitness blah blah. why dont you try beat it on ebike?? will be interested on same route who is faster then ppl can stfu about this achievement. ppl do 1500m at the bikepark on blue trails and are completely exhausted...
  • 4 1
 @Lokirides: yes I could feasibly do all of those on my kenevo. I know your not hating on ebikes, you're just missing the point.

It's not about the software, the software just allows you to alter the assist, and if it gives you less it can do that for longer. It's a question of physics; energy, power output and time. In proper terms, a 500Wh battery will provide 500J of energy per second for 1 hour before it goes flat, or 100J of energy per second for 5 hours, or 50J per second for 10 hours and so on. You can't argue with energy conservation.

What I'm saying is that by lowering the power output a given energy store will last for a much longer time and distance. Yes the rider will have to put more effort in on that ride, and you won't be smashing up climbs at the same speed as you could in turbo, but you can definitely get an ebike to last whatever you ride you want and it'll be easier than on an analogue bike. The biggest I've done is 125km with 10000ish feet of climbing, over 2 days, but on one battery. The assist was so so low, but it still helped me do a ride I couldn't have done otherwise, it made my 180mm coil 50lbs bike climb like my road bike. For example, I've just checked, I've turned my assist down to 1% and the range indicator is saying almost 200km on a full battery.

As I said, I prefer non-ebikes, I'm not doing an "ebikes are great" argument, but loads of people just don't think when talking about them. Yes I can drain the 500Wh battery in 1 hour by smashing up climbs in turbo, but I can also use it to make my heavy, slow 180mm bike pedal like a road bike and ride it all day long. We're all only limited by fitness and the food we take as you said, but given the same fitness and same food you can go further on an ebike, as long as you set the assistance with that in mind rather than setting speed records.
  • 2 2
 @Lokirides: ok that was an unnecessarily long reply! What it boils down to is this: people talk about ebikes having a range, and that whole concept is wrong. Ebikes have a certain range at a given level of power output only; lower the power output and the range increases. It is possible to lower it enough that the range becomes larger than any ride that the same rider can do with no assistance at all. I do it most weekends, so it definitely works!

 @everythingscomingupmilhouse: not hating on Ebikes but I don't think this part is correct:

"Yes the rider will have to put more effort in on that ride, and you won't be smashing up climbs at the same speed as you could in turbo, but you can definitely get an ebike to last whatever you ride you want and it'll be easier than on an analogue bike"

If they were to weigh the same, correct....any added power from the motor you'd be better off, problem is as power goes up so does weight...you need XXJ to offset weight, once the bike cannot supply that anymore (at a bare minimum) you are screwed....that could be 3 hrs or 10 hrs....@Lokirides has a valid point, analog bikes take less energy to ride long distances

 Don’t understand the cable car part. Need more info on why they had to do that. Why not just ride the whole way?
  • 6 0
 Because you have to get up the mountain somehow and there‘s no way you‘d also climb 20k m in 16 h
  • 1 0
 Because climbing damn near 70,000 foot on a bike in 16 hours is impossible, and I’m not sure even an ebike could do that.
