[ PRIVATE GUIDING ]A day in the Mountain,
your way
Chamonix can feel overwhelming if you don't know it — a huge trail network, serious vertical, and endless route choices. A private day takes all of that off your shoulders.
Whether you want to discover the valley's classic trails, run the key sections of a race course, or simply move through wild terrain at your own pace, every day is shaped around your goals, your fitness and what you want from the mountains. No fixed groups, no chasing times — just expert local guidance and the freedom to enjoy where you are.
[ What we offer ]Private guiding
Private trail running
The classic. Discover the valley's finest singletrack, balconies and cols at a pace that suits you. Perfect for visitors wanting to get the most from the terrain, or runners building confidence on technical alpine trails.
FROM€390
Race-course recce days
Racing UTMB, CCC, OCC or TDS? You know the course on paper. Running the climbs that drain you and the descents that wreck your quads is different. We recce the key sections so you arrive knowing exactly where to push and where to hold.
FROM€390
Private guided hiking
Prefer to walk? The same wild trails, local knowledge and safety, at a hiking pace. Ideal for those who want the high mountains without running, or to mix a gentler day into a running trip with friends and family.
FROM€390
Multi day trips
A private trail running holiday designed from scratch — hut-to-hut adventures, the Tour du Mont Blanc, or a custom itinerary in the Alps or further afield. Logistics, routes and pacing handled, so you just run.

[ MEET YOUR GUIDE ]Alistair Crompton
After realising at 39 that he wasn't living the life he wanted, Alistair quit his corporate career, sold his possessions and moved to the mountains. More than a decade later he's still following that passion — trail running, paragliding and ski touring out of his home in Chamonix.
He came to trail running by accident when he arrived in the valley ("a pair of shoes is easier to pack than a bicycle") and, after a string of mid-distance ultras, fell for the rhythm of moving fast and light through wild terrain. For Alistair, time in nature is a form of self-care and running has become a kind of meditation — and that calm, grounded presence is exactly what guests remember about a day in the mountains with him.

[ TESTIMONIALS ]Trusted in the mountains
★★★★★
"Alistair is an exceptional guide. He has so many amazing experiences to share and invites people to enjoy life through trails, running, stories, food, and positive energy. As a guide, he is prepared, organised, informed and relatable. As a person he is so funny and likeable, an immediate friend. He has a unique way in setting the stage for new experiences, while allowing you to experience them in your own way, all in a supportive and safe environment. He has this crazy calming effect to those of us who like to spaz out about things."

“Alistair was my guide on an Alpine running trip last year. He was a major factor in the joy and memories I take from the trip. It’s not just his knowledge and experience in the mountains but he has a unique temperament that mixes adrenaline and adventure with calmness and deep conversation. He will be a major reason why I will keep coming back to the Alps each year.”
Tony T, Australia
★★★★★
“Alistair went well beyond what I would expect from a guide, not only in terms of logistics and local knowledge, but in the quality of emotional presence, attunement, and grounded support that he offered individuals and the whole of the group. His ability to meet people where they were, and hold complexity with steadiness, warmth, and deep sincerity made the experience both accessible and expansive.”

[ FAQ ]Frequently asked questions
-
For trail running you need to be able to run for 3 - 5 hours with up to 1,000m of elevation gain and descent.
Our trips are not performance clinics, but about being in the mountains, taking time to appreciate where you are. However if you like to run fast there will be opportunities each day. And if you like to run slow, we won’t leave you behind.
Also, each of our tour descriptions details the level of running experience and fitness required.
