Three weeks ago, I ran the 2024 UTMB by @UTMBMontBlanc. UTMB is an incredible 109.6 mile race that follows the Tour du Mont Blanc, starting and ending in France while passing through Italy and Switzerland along the way.

I finished in 43:18:07, equivalent to a 23:42 min/mile pace, placing 1217/2761 overall. For much of the race, I was simultaneously amazed by how beautiful the course was and also overwhelmed by its difficulty. Luckily, I was able to harness a lot of energy from the electric atmosphere present throughout the race. In particular, I could not have imagined how many spectators there would be cheering runners on, ranging from huge crowds at the start and finish line, to the multiple scream tunnels near Notre Dame, to individual families sitting outside when we passed by their homes while running through the mountains. I now better understand just how special UTMB is to all of the communities that the course passes through.

On a personal note, I am really grateful I was able to run and the finish the race. I was dealing with a variety of health issues leading up to and during the race, and there were points where I felt like I was close to DNFing. In early July, I had an unfortunate accident where I fractured my skull and jaw. In the following days, finishing UTMB felt like it would be impossible, so much so that I almost cancelled my registration entirely. Luckily I didn't, and looking back now I'm honestly just so thankful that I was still able to go and experience the race fully.

Congratulations to everyone else who ran as well, including Charlie, Eileen, Michael, David, Sam, Lindsey, Kay, Amy, Ivan, Sammi, and Joyce.

Thank you all volunteers and friends who helped cheer and support! We appreciate you! Carmen Brian Sam
