while most races use 20 to 29, 30 to 39, and 40 to 49?

Hi Johan,

Thanks for contacting Triathlon age groups are defined by USA Triathlon (USAT).  USAT is the governing body of triathlon, and most races do their best to adhere to the guidelines they have provided.  In smaller races, some age groups may be collapsed together, but for the most part these are the age groups you will see.  Here is an excerpt from their website:

Age Groups
Age groups are categorized by five-year increments:

  • 18-19
  • 20-24
  • 25-29
  • 30-34
  • 35-39
  • 40-44
  • 45-49
  • 50-54
  • 55-59
  • 60-64
  • 65-69
  • 70-74

If you want to check out their website, here is the USAT age group overview:
There is some great information in there; it’s worth checking out for general triathlon rules and regulations.

Be well.
