What racers and reviewers say
- SlowtwitchRaced 2017 · article · Positive
Report on the 2017 event in Taitung. Conditions were called ideal, the full-distance course record fell by 13 minutes, and Jan Frodeno won the half as a late invitee in 3:48:20, showing the course can be fast on a good day.
“Conditions were ideal”
- Triathlon Magazine CanadaRaced 2013 · article · Positive
Early preview describing a two-lap lake swim in Taitung Forest Park, an undulating two-lap bike between the Carp Mountains and the Pacific, and a run through the city, rice fields and along the promenade. No conditions or opinions given.
- Cheryl Tay blog (IRONMAN 70.3 Taiwan, same lake and roads)Raced 2018 · blog · Mixed
First-person report from the Taitung 70.3 (different brand, same Forest Park lake and Highway 11 area). Wetsuit-optional water just under 24 C (75 F), mostly flat highway with a short steep climb, headwind on the way back, aid about every 2 km (1.2 mi), strict draft marshals and lively spectators. She found it harder than its easy reputation and flagged a 12-hour trip from Singapore.
“Harder than people said, mainly wind and heat”
- Taiwan triathlon race guide (ctyeh.com)Raced 2025 · article · Mixed
Local guide to Taiwan triathlons. For Taitung it describes a bike north along coastal Highway 11 with Pacific views that can be hilly and windy, and a run that is mostly flat but exposed to strong sun late on.
- Taiwan course conditions guide (ctyeh.com)Raced 2025 · article · Mixed
Generic Taitung guide: swim venue changes by year, summer highs of 28-35 C (82-95 F) with 70-85% humidity feel several degrees hotter, crosswinds on South Link roads, some uneven rural pavement and long aid-station gaps on the bike. Written for summer, so April should be milder.
