Character
Loose scree, terrifying speed
The Scree Run is the section that defines Mount Marathon's reputation. From Race Point to approximately 1,250 feet, runners descend 1,772 feet in under half a mile on loose rock, kicking up dust and debris as they go. The fastest descenders reach speeds that aren't really running — it's more like controlled falling. Cuts, bruises, and blood are common; spectators on the lower slope can see and hear the entire field coming down at speed.
The physics of the descent
Runners don't run down the scree — they commit to a controlled slide-run, using the loose rock as a breaking surface while trying to stay upright. The fastest descenders are essentially surfing the scree, making thousands of micro-adjustments per second. Falls are common and often spectacular.
The sound
The Scree Run is loud. Loose rocks scatter and rattle as the field comes down; you can hear the descent before you see it. The crowd noise as the leaders come into view adds to a genuinely electric atmosphere.
Injuries and cuts
Mount Marathon participants sign waivers for a reason. The Scree Run produces cuts from rock edges, abrasions from falls, and occasionally more serious ankle or knee injuries from rolls on loose terrain. Finishing with blood on your legs is considered a badge of honor.
Where to watch
Positioning yourself on the lower slope gives a clear view of the entire scree field above — you can watch from the moment runners leave Race Point all the way to the point they enter The Chute below. Bring binoculars.
Pro tip
This is the section to position yourself for if you want the most dramatic spectating experience. Get on the lower slope early and look up — you'll see the entire scree field alive with descending runners.
