The TRANS-SAVOIE 50/50 is a 6-day point-to-point Enduro Aventure. It’s not a race. There’ll be no overall podium and no official daily ranking. The focus with 50/50 is in discovering and enjoying your ultimate Alpine trails, scenery and adventure, together with a group of like-minded individuals.  

That said, when world-class singletrack points downhill in chunks of 1000m vertical descent at a time, there’s probably going to be more than a hint of rivalry between riding buddies and fellow mountain bikers. But with 50/50, this is not our primary goal. We aware acutely aware of our limited privilege to even be allowed access to such a pristine natural environment in the first place; one which we must share respectfully with others..or as mountain bikers, risk losing that privilege forever.

Ridden or uplifted sections between timed stages (Liaisons) are not timed and your order of start/finish each day is generally free-order (you start and finish each section at your leisure, within a given time window.

All timed stages are predominantly long, downhill single-track sections of technical trail. Liason Stages are a mixture of cruising singletrack and fireroad, mechanical uplifts (ski-lifts), some climbing – with very minimal off bike hiking/pushing.

It’s not a race. There’ll be no overall podium and no official daily ranking…

E-Bike or Analogue?

Increasing the focus on big-mountain adventure emphasises the personal challenge and joy of riding endless alpine singletrack for six days straight, with ski lifts and shuttles taking riders even further out of the bike parks into loamy forests and high Alpine pastures. E-bikes also enable riders who might struggle to complete well in excess of 20,000m vertical downhill laced with unavoidable climbs and liaisons reach all the event’s gold.

Tackling some of the world’s best trails on a regular or electric bike will be a personal choice with benefits to both options, but the communal achievement of completing the incredible 6-day Trans-Savoie Alpine journey will be shared by everyone, no matter your weapon of choice. All days will be specifically tailored too, so that modern e-bikes can complete transfers between descents without charging or extra batteries.

To be clear on that point – a second battery is permitted, but you’ll need to carry it yourself.  The course will be achievable on one battery on most modern e-bikes – when used with a heavy tendency towards “Eco” mode rather than “Full-Power”.

…but some ‘special’ stages will be timed with Sportident chips with individual results published.

Based on feedback from the original tent-based, “move-camp-every-day”  Trans-Savoie format, the new 50/50 adventure will follow a “clover-leaf” style route, moving base 3 times over the week – i.e. every other day.

Over the week, riders will spend 5 nights in comfortable, dormitory-style accommodation, and 2 nights under canvas.

Bedding is provided whilst staying in dormitories of 6 to 8 riders per room.  On camp, each participant is provided with an individual tent and thick camping mattress and pillow, and even a sleeping bag on request, should you not wish to bring your own.

We are very confident that with this new “50/50” approach to accommodation and base-camp re-location (OK then, more like “71/29” for the mathematicians amongst you), riders will retain the feeling of “journeying” and following and epic point-to-point itinerary, but without the significant hassle of packing up and moving base every single day (not to mention the inconvenience of camping for the whole week…especially if bad mountain weather rolls in).

High quality catering is included & provided by local caterers, in association with a team of professionals who have 10+ years experience in catering for hungry sportsmen and women.

Naturally, there’ll be plenty of cool beer and other refreshments available every evening.   This is no elite-level competition, after all, and you’ll certainly work up a thirst every day!

Trans-Savoie is blessed to be supported by some of Europe’s most experienced volunteer Emergency Doctors and Mountain Medics on its crew, with many years of experience in wilderness terrain.  These are backed up by a crew of dedicated, professional mountain event rescue who are contracted exclusively to the Trans-Savoie throughout the week and who provide rescue and safety to many of the Alps’ most extreme events. 

However, the vast and often remote nature of the route (long point-to-point stages, way beyond the bike-park boundaries), dictates it impractical to closely marshall the entire itinerary. The route is clearly marked (signposted at all junctions) and requires no map-reading. A basic level of self-awareness & mountain-sense, is required at all times.  A sweeper system of first-aid-capable backmarkers is used in addition to other safety systems. Riders are advised to be wary of the remote and sometimes isolated nature of the route and therefore to ride accordingly at all times. In addition a general awareness and appreciation of a truly wild and remote mountain environment will lead to an enjoyable and safe finish.  A detailed route-briefing and navigation crib notes will be given to all competitors before each day’s adventure commences.

…supported by some of Europe’s most experienced Emergency Doctors and Mountain Medics

In addition to the sweeper system, a mutual-goodwill spirit is expected of all participants. In the event of arriving to a fellow rider in trouble and/or in need of urgent medical attention or rescue, the entrant is expected to assist and provide assistance / alert the race organisers if not already on the scene.

Similarly, penalties and even outright disqualification will be applied to any rider flagrantly ignoring the safety of any other rider in an emergency situation…or showing disrespect to the fragile natural Alpine environment in which we have the privilege to share with all manner of other local residents (wildlife, farmers, villagers, and tourists alike).  Anything less is certainly NOT the spirit of the TRANS-SAVOIE 50/50!

Cameraderie & Respect for your fellow riders, mountain locals & our environment; are core to our ethos

Riders will depart around 08:30 each day, with a big uplift either by bus (typically 45 minutes) or ski-lifts – or a combination of both. Expect to be out for around 6-9 hours per day (allowing for a lunch break, uplifts, timed stages, rests, and Liaison stages). There will be specific cut-off times for each Liason stage that are for saftey reasons only – not to enforce a fast pace of riding between timed stages (although a reasonable-to-high level of endurance and fitness will be required simply to complete the course within the cut-off time).  Competitors are generally free to proceed into any stage at their leisure and in no particular pre-allocated order of rider.

We took the rule book on conventional events, and threw it out window (of our mountain refuge)

The route follows a heavily uplift-based route, but all entrants should be wary that a good level of endurance is required to complete the event. If you’re on an e-bike, of course you’ll have less to worry about, but extremely long and very physical descents involved in this epic route are also not to be taken lightly. Some timed stages will last up to 20 minutes, not counting any pauses you may take. Think “Megavalanche”, plus a fair amount of climbing, in one morning’s riding. Then repeat for 6 days in a row.
