The 211-Mile Resupply Window That Decides Your JMT Thru-Hike

Six resupply points, four months of field data, and a 14% bonk-rate spike between Tuolumne and Muir. Our route team logged every box, every bear-canister check, and every water-source gamble from Happy Isles to Whitney Portal — and rebuilt the canonical JMT resupply calendar around it.

From the Sierra Nevada Testing Corridor · Issue 187

Gear Lab verdicts, this week's drop.

Every product below spent at least 120 trail miles under testers carrying 28–42 lb loads between 8,200 and 13,150 ft. Bonk-Risk deltas are scored on the N2 1–100 nutrition-pressure index, not marketing copy.
