Why This Race Is Hard For Sodium
The Cumulative Deficit Window
LOTOJA is a temperature swing event. You roll out of Logan at 6 AM in 40F kit and finish in Jackson with afternoon temperatures often pushing 85F. Sweat rate climbs across the day even at the same effort, and most athletes underestimate the cumulative sodium deficit on the back half of the course (Afton to Jackson) where the climbing stops, the heat peaks, and pacing relaxes. Aid stations are well stocked, but the gap between Strawberry summit and Geneva descent is the highest cramping window in the race.
Key Considerations
- Plan two sodium dosing tiers: cool-morning rate for the first 60 miles, hot-afternoon rate for miles 100 to 203.
- The Salt River Pass climb at mile 121 is the most common cramping checkpoint; pre-load 600 mg sodium 30 minutes before the base.
- Aid stations carry standard sports drink (~150-200 mg sodium per bottle). Salty sweaters should carry electrolyte capsules; do not rely on the on-course supply.
- Jackson finish line averages 4-7F warmer than the Afton checkpoint; budget an extra 200 mg sodium per hour for the final 40 miles.

Common Questions
About LOTOJA
How much sodium should I take per hour at LOTOJA?
For an average-profile cyclist targeting a 10-hour finish in typical September conditions, 600 to 800 mg per hour is the working window. Salty sweaters often need 900 to 1200 mg per hour during the afternoon segments (Afton to Jackson). Use the calculator with your actual weight and sweat profile to dial it in.
When does the climate shift from cool to hot?
The first feed zone in Preston is typically still in the morning shade and runs 50-65F. The climb to Strawberry summit warms quickly. By Montpelier (mile 80) most years are 70F+. The Snake River Canyon descent at Alpine is the hottest segment of the course, often peaking at 85-90F in early-September afternoons.
Is LOTOJA hot enough to require pre-race sodium loading?
Yes, especially for salty sweaters. The combination of a 10-13 hour effort, late-day heat, and limited shade after Alpine makes pre-race sodium loading meaningfully impactful. Add 1000-1500 mg sodium in the 24 hours before the start, weighted toward the night-before meal and race-morning breakfast.
