What racers and reviewers say

  • Slowtwitch NewsRaced 2023 · article · Mixed

    Pro-race coverage from a moto marshal: the designated acclimation zone with no closure limit was a standout for cold water. Bike roads were bumpy desert tarmac with good police at intersections, some tight out-and-backs, and a drafting pack. Roads in and out were shut 06:00-09:30 and early shuttles were hard.

    “designated acclamation zone”

    Eric Wynn
  • Run Paige RunRaced 2023 · blog · Positive

    First-person report: 56 F (13 C) water felt harsh but passed in about five minutes; mostly flat good-pavement bike with a notable climb near mile 53 (km 85); hotter, hillier two-loop run than expected. Unclear parking, a two-mile (3 km (1.9 mi)) walk and a long split-transition briefing, but wetsuit volunteers and heated tents helped.

    “one of my favorite triathlons I've ever raced”

    Paige
  • Slowtwitch forum threadRaced 2022-2025 · forum · Positive

    Posters from 2022-2025 call it fun, fast and flat with a chilly but manageable swim. Several report 10-15 mi (16-24 km (9.9–14.9 mi)) of rough pavement, a hillier-than-expected golf-course run, spectator shuttle problems, two transitions, and pricey Indian Wells hotels.

    “the swim is chilly but not freezing”
