Who is racing in St George?
With the postponement to February 2022 of the IRONMAN World Championship in Kona, St. George has now become the ‘A’ race for many endurance athletes this year, with all eyes on the big showdown on September 18.
Several athletes have already experienced the course this year – Lionel Sanders and Daniela Ryf earned victories there back in May. Canadian Sanders of course enjoyed that epic duel with American Sam Long before finally claiming his win.
There are certainly some enthralling storylines for triathlon fans to get their teeth into heading into the event – now the first of two consecutive years where St George will host the event (2022 is also locked in).
Olympic and World Triathlon Championship Series champion Kristian Blummenfelt is set to compete in his first middle-distance race for almost two years. Will his speed translate to making history by winning all three an a single season?
The aforementioned Ryf meanwhile is targeting her sixth 70.3 world title as she bids to put the miserable memory of that Collins Cup defeat by Taylor Knibb behind her (Ryf raced despite waking up unwell on race day in Slovakia).

Knibb meanwhile is set to take up the slot she earned by finishing second behind Emma Pallant-Browne in Boulder recently?

Can British superstar Lucy Charles-Barclay finally make it to the top of the World Championship mountain after four second-place finishes in the past – one at 70.3 and three at the IRONMAN World Championship in Kona?

On the men’s side can Gustav Iden – who was in imperious form at the Collins Cup last month – defend the crown he won so brilliantly in Nice in 2019? Or will his compatriot Blummenfelt continue to carry all before him in 2021?

Young guns George Goodwin, Magnus Ditlev, Daniel Bakkegard and Kyle Smith are among the men who carry the hopes of the ‘next generation’ while Sanders, Javier Gómez, Michael Raelert, Tim Reed and co. provide formidable veteran opposition.

The course: St. George, Utah
As those who took on IRONMAN 70.3 St George earlier in 2021 already know, the course is a challenging route which will require peak performance to contend at the front end of the field.
A 1.9km swim in the Sand Hollow Reservoir starts the competitors off – a single-loop course finishes adjacent to the start line with T1 awaiting the field on the shore.
A technical bike course, 90.1km in length, takes the competitors around the south end of Sand Hollow Reservoir before turning north, then west towards the more technical part of the course.

The final 30km of the bike starts with a relatively steep climb of some 1000 feet over 10km before dropping back down on the final 20km of the bike into T2.
The 21.1km run takes the athletes on a two-loop course with two 500-foot climbs and descents to test the legs in the final stages.
