St. George 70.3

St. George, UT · USA · May · 70.3

A true strength course: climbing legs and heat tolerance decide it, not flat speed.

🏊 Swim

1.9 km

Cool reservoir swim at Sand Hollow.

Strategy: Clear water and a wetsuit make for a calm swim. Bank energy here — the bike will take it all back.

🚴 Bike

90 km · 1200 m ↑

Big desert climbs with fast descents — a real test of bike fitness.

Strategy: Pace climbs by power/effort, not ego. Riders who chase the climbs here cannot run a step afterwards.

🏃 Run

21.1 km

Hilly town run that bites in the heat.

Strategy: Walk the steep up-hills with purpose, run the flats and downs, and drown yourself in ice and fluid.

Template cutoffs updated 2026-06-22 basis: rolling Official Athlete Guide ↗

Standard 70.3 cutoff structure shown as a planning template — most 70.3s allow ~8:30 overall from your rolling start, with a swim cutoff near 1:10 and a bike cutoff near 5:30. Mid-bike and mid-run cutoffs vary. Always confirm the exact gates and clock basis in this event’s Athlete Guide for your race year.

Targets by level

Finish-first

Beat every cutoff with margin. Swim relaxed, ride well within yourself, walk-run the climbs, and never stop fuelling.

Sub-6 / strong age-grouper

Hold steady race power on the bike, protect the run, and execute transitions cleanly. The run is won by what you did NOT do on the bike.

Competitive age-group

Sharp swim, disciplined high-end bike to your durability, and a negative-split run. Every transition second counts.

First-timer risks

  • Over-biking the climbs and having nothing left to run.
  • Heat on a hilly run — the classic St. George blow-up.

Packing & prep

  • Climbing-friendly gearing (compact / wide-range cassette).
  • A heat plan: salt, ice strategy, and a realistic run pace.

Race-morning timeline

−3:00 h Wake, main breakfast, sip fluid. Familiar food only.

−1:00 h Top-up carbs + fluid. Wetsuit half-on, short warm-up.
−15 min Optional gel, get to the swim corral, find your seed pace group.
Gun Start controlled — the first 300 m of the swim is not the race.
