Watch out for

- Sprint swim is only 350 m (0.22 mi), so times do not compare with standard sprints.
- Bike is hilly over three loops; one racer found it chilly at 13 °C (55 °F).
- Only two 2022 racer reports found; little independent word on parking or packets.
- The 2027 edition is listed as Cal Tri Oro Valley; organiser and details may change.
