Challenge Shanghai 2026
A middle-distance triathlon at Haiwan National Forest Park in Shanghai: a two-lap swim, a four-lap bike along Hangzhou Bay and a four-lap trail run.
3 weeks to race day: the sharpening window
A full build no longer fits, but a sharp one does. This close in, the job is specificity and freshness: race-pace touches, open-water or brick rehearsal, and a taper your nervous system actually absorbs. No heroics; arrive fresh.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Build my pacing and preparation plan.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“The bike is four laps along Hangzhou Bay and the run is four laps on park trails, so plan fuelling around the repeating loops. The organiser publishes no total distances or elevation figure on the page read.”
