Just updated the @kilianj map with the Shasta and Rainier efforts for the finale of his States of Elevation project: https://t.co/37NvUNBpZF This one a fun one to put together and I learned some new skills along the way.

Testing out using GPX files to calculate performance vs other runners. The chart below illustrates Hans Troyer, David Sinclair, and Stephen Kersh at JFK 50 Mile hit last weekend. You'll notice the first gap opens up after the Appalachian Trail section when Hans rolled through

Feel free to check it out here: https://t.co/MO5n9iklaR A lot of tweaks to be made, but I always like to release something rather than getting it perfect on the first try.

Or normalize the starts to directly compare regardless of starting elevation:

You can also display the slope grade:

Built a new tool to help compare race/route elevation profiles. While they don't tell everything, I wanted to visualize how the climbs of a race I had done compared with those of an upcoming one. The visual here displays Broken Arrow 46k with Speedgoat 50k.

Here's a GPX replay of the 2025 Javelina Jundred. The replay includes the top 7 male runners (all sub 14 hours): Will Murray, David Roche, Canyon Woodward, Chris Andrews, Caleb Bowen, Zach Hauer, and Sage Canaday. Tara Dower was 7th overall, but didn't publicly post so isn't

Course looks 😍

Added @kilianj's day 5 Desert Ride, Norman's 13, and White Mountain activities to the Kilian Map. Also made mobile view less bad: https://t.co/37NvUNBpZF

The @kilianj States of Elevation map has been updated with his latest series of rides across the desert from Colorado to California: https://t.co/37NvUNBpZF @aidstationfireb @dylanbo

I made an interactive map of Kilian Jornet's @kilianj States of Elevation project: https://t.co/37NvUNBpZF - displays the tracks / route - differentiates between run / ride Obvious upgrades: - display where the 14ers are - better map controls - link to activities on Strava

FYI am also posting these to Youtube:

Recreated the Tor des Géants flyover with improved quality and included the elevation profile...

Let's preview The Bear 100. Taking place September 26-27 2025, The Bear 100 is point-to-point course weaving through the pines, golden aspens, and red maples traversing 100 miles with 22,816 feet of climbing, reaching a maximum elevation of 9,043 feet, a minimum of 4,852 feet,

Flyover preview of the Pine to Palm 100 Mile Endurance Run... "A remote and rugged classic point- to-point course -- traversing Southern Oregon's Siskiyou Mountains. Starting in Williams, OR the course winds it way east to Ashland, OR on a mixture of single track trail and dirt

See the chart for this here:

Let's see where Francesco Puppi and David Sinclair pulled away from Drew Holmen during the 2025 Men's CCC race. Looking at the splits only, you can see where this happened (between La Fouly and Champex-Lac), but using GPX we can reverse engineer the moment to see that it was

Here's when Tom Evans decisively built his lead on Ben Dhiman climbing from Arnouvaz to Gran Col Ferret. From this point on Tom extended his lead over the entire field by throwing down the fastest split in race history from Courmayeur to the finish in Chamonix (10:53:38).

@simeonGriggs do you approve of the elevation profile yet

Preview the course of the 2025 WMTRC Short Course 45k. The race takes place in Canfranc-Pirineos, Spain and covers 44.5 km race with 3,657 meters of elevation gain. Made a few style upgrades for the elevation profile. Next updates will include checkpoints on the elevation
