TRIATHLON · EXPLAIN IT SIMPLY

What is a triathlon?

A triathlon is one continuous race: a swim, a bike ride and a run, in that order, with quick changes in between. Races run from sprints of about an hour to the Ironman, a day of ten hours or more.

The distances

Triathlon comes in four common sizes. The names “Ironman” and “70.3” come from the total distance in miles.

How race day works

  1. Before dawn. Check the bike, set up the transition area and drop off the gear bags.
  2. The swim. Open water in a lake or the sea, in a wetsuit when the water is cool.
  3. Transition 1. Change from swim to bike gear.
  4. The bike. No drafting, so each athlete rides alone against the clock. Eating and drinking happen on the bike.
  5. Transition 2. Change into running shoes.
  6. The run. The first miles feel strange after the bike. Pacing and fueling decide how the last miles go.
  7. The finish. The finish line clock shows the total time for all three sports and both transitions.

Age groups and world championships

Most athletes race in an age group, ranked against others in the same five-year band (for example M45–49). Ironman-branded races award a limited number of qualifying slots in each age group to the Ironman World Championship in Kona, Hawaii, and to the 70.3 World Championship, which moves to a new location most years.

Our path

  • Kona three times for Sherwick (1998–2000) and three for Jami (2000, 2002, 2011).
  • Five straight 70.3 World Championships for both of us, 2011–2015: Henderson three times, Mont-Tremblant and Zell am See.

Honors

  • USAT All-American: an annual honor for top age-group results.
  • Ironman All World Athlete: a season-long recognition program for age-group athletes.

Our Ironman finishes

Every Ironman finish in the archive: 19 for Sherwick and 15 for Jami. The fastest time for each of us is highlighted. Ironman New Zealand 2006 was shortened to a half-distance duathlon and counts as a finish for both of us; at full distance the totals are 18 and 14.

† Kona 2000: I got my electrolytes all wrong and was vomiting at the end of the bike and throughout the run. Jami caught up to me at Henry St. and we finished together.

Kona 2000 was the day we finished one second apart. Jami did not finish Ironman Canada in 2005 (severe dehydration), and Ironman Lake Tahoe was cancelled in 2014.
