The facility of knowledge is that it offers us proof and inputs that tell our perspectives and choices. Knowledge permits us to transport past anecdotes and intestine emotions. Once in a while the knowledge confirms what we prior to now suspected, and different occasions it offers us solely new insights.
Traditionally, we have now checked out aggregated information for this column. It’s enabled us to talk about developments throughout a couple of years, races, and runners. This month, we’re the use of information to talk about person runners.
With UTMB and the UTMB Mont Blanc pageant simply across the nook, we picked some tales associated with that team of races the place we expect the knowledge permits for a deeper appreciation of somebody’s efficiency — whether or not that efficiency was once one you already knew was once spectacular, or it’s a completely new perception.
[Editor’s Note: We kindly remind readers that the Running the Numbers column is a just-for-fun analysis. While we always endeavor to analyze accurately, we limit the scope of each article in order to make the work doable for author Mallory Richard, and the results digestible for readers like you.]
Ildikó Wermescher and the 2022 TDS
The place do we commence? Ildikó Wermescher is a Hungarian path runner and ultrarunner who lives in Germany. She excels at mountainous races, however a prior top-10 end on the Western States 100 proves she has leg pace on height of her staying power, mountain climbing talent, and common toughness.
It’s difficult to pick out a unmarried efficiency to focus on Wermescher’s talent in the case of lengthy, tricky ultras. She received the 2022 Path Andorra 100k occasion, and positioned 3rd in 2023 — however advanced on her earlier time via some 28 mins. Over that very same length, she additionally boasted a win on the 2022 Istria via UTMB 110k, and podium finishes at Restonica Path via UTMB 66k and Path Alsace Grand Est via UTMB 110k.
Most likely Wermescher’s maximum spectacular efficiency at a UTMB race is her fifth-place end on the 2022 TDS, which takes position right through the UTMB Mont Blanc pageant. The TDS runs for 145 kilometers (90 miles) from Courmayeur, Italy, to Chamonix, France, and is administered on extra technically difficult terrain than the reasonably longer UTMB direction. Wermescher completed in the back of 4 different elite athletes: winner Martina Valmassoi, Claudia Tremps, Katharina Hartmuth, and Julia Rezzi.
What made Wermescher’s consequence stand out is she was once 57 years outdated on race day, hanging her conveniently within the grandmasters (age 50-plus) age class. The DUV Extremely Marathon Statistics database estimated that Wermescher’s completing time of 24:38:45 is the an identical of nineteen:57:30 if the efficiency is age-graded. For context, Valmassoi’s successful time was once 22:42:47.
The DUV web site has a strong rationalization for why and the way it age grades runners’ occasions, mentioning analysis to give an explanation for that “an athlete of 55 years can reach simply 85% of the efficiency of a 30-year-old athlete.” I’d inspire you to learn the reason for your self as a result of I’m no longer a physiologist, however I’m a Wermescher fan.
Zachary Friedley on the Val d’Aran via UTMB Sky 15k
Zachary Friedley, a certified path runner and founding father of the non-profit Born to Adapt, was the 1st above-knee blade runner to begin and end the 2023 Val d’Aran via UTMB Sky 15k. An established athlete, the American took up path operating as an grownup and has made it his undertaking to create alternatives for extra adaptive athletes to find path operating.
In 2022, he finished MCC on the UTMB Mont Blanc pageant, which covers 40 kilometers (25 miles) with 2,300 meters (7,500 toes) of elevation acquire, and he’s these days making ready to finish the race for the second one time.

The United Countries Division of Financial and Social Affairs stories that roughly 15% of the worldwide inhabitants lives with some type of incapacity. Individuals with disabilities revel in discrimination, obstacles to becoming a member of the personnel, and different types of exclusion. The United Countries notes that, the world over, individuals with disabilities are underrepresented within the office and are under-represented in upper schooling amongst international locations within the Group for Financial Co-operation and Building (OECD).
It’s in opposition to that backdrop that Friedley is selling get admission to and inclusion in path operating for adaptive athletes. He’s running with race organizations to create insurance policies and function classes that facilitate participation via adaptive athletes. Within the absence of the ones efficiency classes, the present participation charges of adaptive athletes are tricky to measure and even estimate.
Anke Drescher and Didier Delemontez and Their Many UTMB Finishes
Should you apply this column carefully, it’s possible you’ll know I like it when folks go back to the similar occasion time and again. To me, those veterans play an important function in construction the tradition and surroundings that surrounds a race, giving it continuity from 12 months to 12 months.
Anke Drescher is a grandmasters path runner from Germany. She was once there in 2003 when the first-ever UTMB was once held, completing the 153-kilometer (95 miles) direction in 36:42:52. She was once certainly one of best 67 finishers. She has been on the beginning line nearly annually since, racking up 15 UTMB finishes from 15 begins. Drescher advanced on her first completing time via completing in 36:13:03 in 2007, even if the direction was once then 10 kilometers (6 miles) longer.
Robust, constant efficiency at UTMB seems to be a hallmark for Drescher, and she or he for sure transfers the ones qualities to different occasions, racking up a couple of finishes of the grueling, 200-plus-mile Tor des Géants through the years.
Reviewing my spreadsheet, France’s Didier Delemontez stood out for a similar explanation why. After completing nineteenth within the inaugural race in 2003, it seems that Delemontez started a love affair with the race, returning any other 15 occasions. When he closing entered the race in 2019, on the age of 61, his completing time positioned him within the height 11% of all male finishers.
Yu Lei and the Grand Col Ferret Climb at UTMB
A weblog submit at the Strava web site describes the climb up Grand Col Ferret as “most likely probably the most iconic climb, the person who each and every runner – elite and newbie alike – dreads” within the UTMB. Over 4.2 kilometers (2.6 miles), runners climb 750 meters (2,450 toes) to the very best level within the race.
Runners have already lined 99 kilometers (61 miles) once they depart the checkpoint at Arnouvaz to start out the climb, in order that they aren’t precisely feeling contemporary. Unsurprisingly, this is a phase of the race the place many runners in finding themselves suffering to stick on function tempo.

When Yu Lei, of China, first ran UTMB in 2014, the splits display he took 4:42:36 to climb from Arnouvaz to Grand Col Ferret. Lei returned to UTMB each and every of the 4 following years, and in the end whittled his time on that slope down to one:27:27 in 2018. For context, Tim Tollefson had the quickest break up from Arnouvaz to Grand Col Ferret that very same 12 months, achieving the highest in 59:13. Lei went on to complete in 35:43:54. Tollefson didn’t end that 12 months, struggling a fall, however completed at the podium within the two earlier years.
Ludovic Pommeret and the 2016 UTMB
France’s Ludovic Pommeret, then a pc engineer whose pastime was once being an elite path runner, received the 2016 UTMB. Shall we forestall there and also you’d be inspired, however you’d fail to notice the juicy main points that make his win stand out.
As Pommeret defined to iRunFar in a post-race interview, after beginning sturdy and operating within the lead, he had serious abdomen problems 3 hours into the race that decreased him to a strolling tempo for 3 hours.
Having entered the race as a podium contender, he was once lower than a 3rd of the way in which during the race when he set his expectancies apart: “Within me I didn’t imagine. Then I noticed that I’d no longer end the race, or I’d end the race however possibly I’d sleep for one night time for 4 hours after which proceed later.”
He was once in fiftieth position on the 50-kilometer (31 miles) mark — remarkably a complete hour in the back of the lead — however clawed his as far back as in the end win the race.
