UTMB® (Ultra-Trail du Mont-Blanc®)

2013 sees the 11th edition of this race which is now well established and popular the world over. It is now considered by many the most prestigious ultra.

The UTMB® is limited to 2300 competitors. Only experienced ultra-runners can take part in this race and strict rules and a points system are in place to ensure this!

To enrol for the UTMB® participants must first have aquired a set amount of points by completing races from a list supplied by the organisers. In addition to the demanding qualifying rules, a lottery is in place to deal with the many applicants.

The start time ensures that all the participant will experience large stretches of night running, the slower finishers going through two nights before reaching the finish!

In recent years (2010 & 2012) the race had seen bad weather affect the race and the organisation has now put comprehensive plans in place in the case that adverse conditions should make it unsafe to proceed with the original route.

Britain's Lizzy Hawker is without doubt the queen of this event, having won it an incredible five times to date, placing second another time too! In 2010 Jez Bragg also won the race, and British runners make up a big percentage of the field.

CCC® (Courmayeur Champex Chamonix)

Now in its eighth year, the CCC® is no longer just a step-up or side-show to the UTMB®, but attracts world-class athletes as well as a sell out field of dedicated ultra runners.

Like the for UTMB®, participants need to prove that they have some experience, but the points required to take part in the CCC® are a lot easier to obtain than for the UTMB®.
Apart from the first monster climb, the route follows the second half of the UTMB. While the winners will be finishing in Chamonix in the evening, many participants will be running into or through the night!

TDS (Sur les Traces des Ducs de Savoie)

Now in its fifth year, the TDS was added to the programme in 2009, but was cancelled in 2010 due to bad weather. In 2012 however the TDS was the only race which went ahead without any changes due to the adverse weather experienced in the area.

The TDS sets off from Courmayeur in an clockwise direction and takes in some higher ground than the first half of the UTMB®, really testing those climbing legs! Despite the longer time allowed for runners to complete the event, compared to the CCC®, this is not an easy option!

The beautiful mountainous route aside one of the many attractions of the TDS is that it sets off two days before the two above races, so participants can collect their finisher's gillets, have a sleep, drink a coffee and bask in their glory whilst watching the other races in progress!

Participants need to prove that they have some experience, but the points required to take part in the TDS are a lot easier to obtain than for the UTMB®.

PTL (La Petite Trotte à Léon)

This is a real monster! This race his completed by teams of 2 or 3 participant who need to be completely self-sufficent in some very testing terrain! La Petite Trotte à Léon is an "enlarged Tour du Mont Blanc", far from beaten tracks taking participants on difficult paths sometimes even non-existent; it includes the crossing of numerous cols (passes) and summits of between 2500 and 3000 metres altitude. At the finish, there are no results or prizes...

Not only the runner's endurance will be pushed to it's limits in this event, but also their knowledge of the mountain environment, their ability to navigate and control their efforts and resources! Above all, their team spirit will be tested to the max.

The route is different from one year to the next; it is not way-marked but will be mapped (GPS tracks and maps supplied). Teams are required to manage their own progress, refreshments and rest time as they wish. To do this they must use the local infrastructure of refuges and villages (no back-up vehicles or assistance allowed).

To qualify at least one member of the team must have finished, in the past, the UTMB® or the TOR DES GEANTS, one of the previous PTL™ or even the 2012 TDS™. The organisers may consider alternative qualifications.

All of the races finish in the square in Chamonix under a huge finish line banner. So from Wednesday evening, when the first TDS finishers arrive, to the Sunday afternoon, when the last UTMB finishers come in, Chamonix provides the beautiful backdrop to hundreds of emotional scenes as loved ones are greeted by friends and families. The majority of runners are also greeted personally by the organiser, Catherine Poletti.

As well as big races for grown-ups there are also 5 races for children aged 3 – 13: the micro CCC (400m), mini CCC (600m), mini TDS (1200m), mini UTMB (1800m) and the mini PTL (3km). These all take place on the beginners’ ski slope in Chamonix on the Thursday before the CCC and UTMB kick off and provide a good distraction for nervous runners, as well as a fun activity for families who’ve travelled with them.
