MTB Prologue

Discover the detailed map of the course with all the relevant information
   


• Total distance : 3,3 km

Explosive speed is not enough, only a careful management of your effort will lead to success. It is an ideal opportunity to get your bearings on the terrain of the Cantal and test the power of your “engine”!

53-km Cross-Country


• Level of difficulty : 4/5






Discover the detailed map of the course with all relevant information
   


• Total distance : 53 km
• Positive altitude diffrerence : 1870 m
• Time limit : 7 hours 30


After an uphill start in which competitors jostle for place, you will get to grips with an initial fairly fast downhill section, with some single-tracks on the menu. The next part will be more physically demanding, but, by climbing uphill, will offer you the opportunity to admire the superb landscapes of the Cantal. There are no real technical difficulties, but with a significant uphill gradient and considerable distance, this route is reserved for regular mountain-bikers.

NEW FOR 2010: the route has been substantially changed over 20 km for better riding and to limit the amount of carrying or pushing.


• Start time : 10 : 30 a.m.
• Open to those of 18 years of age and over
• Fees: €34

86-km MTB Marathon


• Level of difficulty : 5/5






Discover the detailed map of the course with all relevant information
   


• Total distance : 86 km
• Positive altitude difference : 3200 m
• Time limit : 11 h


The leading event of the Oxygen Challenge for mountain bikers, this 84-km route will take you through some of the finest spots of the Cantal Mountains, at the heart of Europe’s biggest volcano.

The first 48 kilometres are identical to the 53-km cross-country race. After this “warm-up” the participants will get to grips with an additional loop that leads them to the fantastic tracks along the range’s mountain ridges. They will start with the Voie Romaine, a long, technical but fun descent, before tackling the last difficulty of the day and returning to the resort. This intensive race is reserved for very well trained competitors who can handle the length of this marathon, significant differences in gradient and highly technical difficulties of the last 38 km.

NEW FOR 2010: the route has been substantially changed over approximately 40% of its distance for better riding and to limit the amount of carrying, especially towards the end.


• Start time : 8.a.m.
• Open to those of 18 years of age and over
• Fees: €42

Saturday 15 May 2010

A new distance for your 1st mountain challenge!
The initial part of the circuit, with a mainly downhill profile, will allow you to warm-up.

You will then return to the resort via fairly quick tracks, especially in the last 5 km. This route does not boast any major technical difficulties and is accessible to all mountain-bikers.


• Stat time : 11 a.m.

This endurance race is accessible to all mountain-bikers, especially those from the Cross-Country discipline. It includes undulating special sections, with mainly downhill profiles, on quite a wide variety of terrains (mountain ridges, woods, etc.). Like in 2009, the semi-rigids should again do well!
