Our Story


We got lost

Down in Chile: two of our co-founders, Max and Moisés, meet by getting lost during a 50k race.  Meanwhile, over in Morocco, Vert.run’s third co-founder Kirsten starts her photography career by shooting an ultramarathon for the New York Times.


Max and Moisés both go on to become sponsored by The North Face Chile, climb crazy peaks together and start living for (and from) trail running. Meanwhile, Kirsten moves to Berlin, Germany and photographs lots of trail running for lots of publications. 


Max, Moisés and Kirsten go on a two-week expedition together in Patagonia for The North Face Chile. Max and Moi are shooting for an FKT of Cerro Castillo, and Kirsten’s there as the photographer. After the expedition, the trio heads to a brewery where Vert.run is born with the mission of sharing our trail running love with others.


baby steps

Vert.run starts out as a mailing list. Max, Moi and Kirsten work behind the scenes like the Wizard of Oz to get free training plans to everyone. We hit 6,000 trail runners on our email training plans and decide: it’s time for an upgrade.


We team up with our fourth co-founder, Cristóbal Forno to show us the business ropes of running a startup. We launch the first version of our training platform, which is the Vert.run that you know today. 


We start partnering with professional trail runners like Pau Capell, Hillary Allen, Lucy Bartholomew, Ryan Sandes, Ruth Croft, Tom Evans and more to create awesome, affordable training plans designed by the pro athletes we most admire.

Today, over 85,000 runners like you from 100 different countries (yes, for real!) train, connect and stay inspired with Vert.run

Meet The Team



Kirsten first came to trail running through the lens of her camera, as a photographer whose first-ever publication–about an ultramarathon!–was in the New York Times when she was 19 years old. She loves steep, technical trails and long distance road biking.

Kirsten is most proud of the time she biked 120 miles with 12,000 feet of vert in one shot from her house in Annecy, France to Aosta, Italy.


Moisés Jiménez


Moisés is an electrical engineer and professional athlete for The North Face. He spends a solid number of hours each day running on trails, which has taken him to races all over the world and led to some awesome results and wins in competitive races. (Plus, even though he’s our CEO, he’s also a Vert.run coach!)

Moisés is most proud of finishing 16th at UTMB, and top 10 at Lavaredo twice.

Max Keith


Max grew up biking in the desert in Chile, and then jumped to the trails. He got hooked on trail and ultrarunning, and has great trail results around the world. Max’s motto: The more technical the trail, the better.

Luis Carlos Chacón


Luis is a marathon and Ultramarathon runner from Costa Rica who’s passionate about vegan cuisine. Luis doesn’t just build software: he understands and applies his needs as a runner to make the best possible training platform for us, while balancing coding work and trail running.

Cristóbal Forno


As a father of two daughters and founder of multiple successful companies, Cristóbal still finds time to run and complete at least two 100 mile races per year. In 2017 he ran Western States in under 24 hours.

Francesco Puppi


As a child growing up in Italy, Francesco used to go hiking and trekking with his family all the time. He grew up right next to the mountains, and today he’s a professional trail runner for Nike.

Fran is an incredibly attentive, caring Vert.run coach and he enjoys guiding his Vert.run athletes of all levels. 

The race he’s most proud of is the world mountain running championship in Patagonia in 2019, where he was 2nd to Jim Walmsley.

Manu Ramirez


Manu is originally an engineer turned trail running coach, and is probably the biggest smile on the Vert.run team! He’s one of our awesome Vert.run coaches, and his positive energy is contagious. 

Manu has run more than 35 ultramarathons around the world (from 50k up to 170k) and he’s very proud of his recent degree in sports psychology, which allows him to give his Vert.run athletes even more solid support.

Steve is one of our awesome Vert.run coaches, who enjoys working with his athletes to help them achieve goals beyond what they thought were possible.

Steve started running over twenty years ago and has used it to not only get in shape, but to develop pride in everything his body (and mind) can accomplish.

He has completed races ranging in distances from 5k to Ultramarathons. Running is a lifelong passion for Steve, and he enjoys helping others develop a rewarding relationship with the sport.

He likes to exercise to stay fit and healthy–and in his free time he loves cooking, especially baking!

If you have a why, Martin will have a how. His mission at Vert is to work with pro athletes and race directors to create meaningful, sustainable relationships.

When he’s not working for Vert, you’ll either find him commenting live at the Golden Trail World Series or UTMB World Series or running in the mountains trying to keep up with his partner!

Martin feels the most alive when free to venture in uncharted territory, challenge the status quo and step outside his comfort zone.

France 🇫🇷



Dave is passionate about making a positive impact personally and professionally by supporting community based product development at mission-driven companies.

He is also a lifelong (slow!) runner who loves getting out and exploring urban and mountain trails.

Dave is most proud of completing his first 50k ultra trail run at age 60 with help from the Vert.run app, plan, coach and community!
