Jakob grew up in the Swiss Alps in Switzerland literally next to the Swiss Alps 100 course. He moved to the US in 1998. He founded the Swiss Alps 100 to share his love for the Alps and allow runners from all over the world to experience his childhood paradise.

He is an avid runner who started running in 2005. Since then he has completed over 100 Ultramarathons and 79 marathons. In Switzerland, he has run the Aletsch half-marathon, the Lausanne marathon, the Zürcher marathon, the Swiss City Luzerner marathon, the Zermatter marathon, the Zermatter ultramarathon, and the Zermatt Ultrak "Sky" 49K.

Jakob currently resides with his family in California.

Marc's love for the mountains began as a child with skiing. In good winters he was in the snow 3 times a week. To fulfill his boyhood' dream of flying, he started skydiving and made about 300 jumps. After serving as an officer in the Swiss military in the Alps, he became a long-distance triathlete during his law studies. Well, you guessed it - years later, the mountains and the air took him back. After a few years with ultra trails, he started paragliding and hike‘n‘fly!

Marc lives with his family in Zug and has an IT law firm. He also works as a lecturer.

Mirco Weiss was born in Winterthur, Switzerland, and has lived in the beautiful Valais since 2012. He completed an apprenticeship as a cable car mechatronics engineer, followed by further training as a cable car specialist. Since 2021 he works as technical manager in a hotel in Zermatt.

He has been interested in first aid since childhood. In 2016, together with some friends, he founded the Upper Valais Military First Aid Association, of which he is president. In 2017, he completed the SMSV training to teach the various first aid and BLS-AED courses to the public. Since 2018, Mirco has been in charge of the Ambulance and Safety section of SwissAlps100, leading the operations and ambulance services with the SMSV Upper Valais. The association is supported by volunteers from the National Ski Patrol.

Besides first aid, he loves to spend his free time in the mountains.

Great visionaries have to be helped to put their ideas into practice. Jakob is such a visionary. As a homesick Valaisan, he makes an immense effort for our tourist region. His concept for runners from all over the world is unique and valuable for us and the region.

Born in Valais, Nathalie grew up in Brig with her hometown in Fiesch and is deeply connected to the region and its people. Her interest in running started in 2010 but it wasn’t until 2016 when she did her first trail run in 2016 in Grindelwald that she found her passion. Since then, she has done other races and continues to enjoy the great beauty of the Swiss Alps. She brings her love for and intimate knowledge of the Swiss mountains to actively support the Swiss Alps 100.

Today she lives in the Bernese Oberland, but often likes to visit home in summer by airmail, in a glider.

Fred is the Swiss Alps 100 sweeper for the 100 miles race course. He is a passionate mountain runner who enjoys the solitude of the big mountains, preferably on the long and technical distances. He never says no to a good chat and a beer on the trail and is eager to spend some time just embracing the big stuff and helping the back of the pack to get within the cut off time.

Fred is also a member of the National Ski Patrol and is educated in mountain rescue and first aid. In the winter he is bending the knee in telemark turns and does ski mountaineering.
