IRONMAN 70.3 Nelson Mandela Bay 2027
A 70.3 in Nelson Mandela Bay: a swim in Algoa Bay, a bike the organiser rates among the best and a flat two-lap beachfront run.
17 weeks to race day: a full block fits
This is the sweet spot. A complete 12-week recovery-led build fits inside the runway with room for a base phase in front. Anchor the block to race day and every week between now and then has a reason.
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.
Check whether my runway is realistic.
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 organiser describes a flat, two-lap beachfront run after a bike it rates as spectacular, so pace the bike to run well. No elevation figure is published.”
