Lucy Charles-Barclay finally claimed the title she craved last Saturday when she destroyed an elite field to win the 2021 IRONMAN 70.3 World Championship in St George.
The 28-year-old British star produced the fastest swim, bike and run as she came home more than eight minutes ahead of her nearest rival. It was an absolute demolition job.
Red Bull athlete Lucy sat down with us to provide a detailed debrief on her day as it happened in Utah. From inception to execution, it was she admitted โpretty much a perfect dayโ.
The strategy โ all about Lucy
โWhen we sat down before the race to try and come up with a strategy for the race, we decided that we would just focus on me the whole day and try not let my mental state be influenced about what anyone else was doing. If I was caught on that bike then it would be like โthatโs fine, weโre doing my thing all day longโ.โ
The swim โ better than expected
โObviously the swim I just did my normal thing โ I wasnโt sure how much of a gap Iโd get over those girls. Particularly with Taylor Knibb in there, sheโs got the ITU background, so youโre not sure how quick she might swim. But to come out with the lead that I did was pretty unexpected.
โI think one of the big things that people donโt realise is the difference that a wetsuit makes. When Iโve raced previously, the girls who wear wetsuits, it makes it that tiny bit easier for them to keep on my feet. My advantage in a wetsuit is minimal maybe compared to slightly weaker swimmers.
โSo actually as soon as I ever do a race and they say swimskin, Iโm the first one celebrating โ knowing actually this is definitely gonna help me out because I can swim almost just as well in a swimskin as a wetsuit. So I knew that if I could get that gap early, that gap was never gonna get back onto my feet so it was about pushing the pace early which is fine for me. I always just try and push that pace early, and then just settle into my rhythm.

โSo I did feel good on the swim, I felt like I was in control, I wasnโt frantic with my stroke, I was just relaxed. My main thing is always to just make sure Iโm swimming the right way so Iโm not wasting any time and I felt like it was a good course, it was well marked out.
โThey had actually numbered the buoys, so on the way back they were counting down, so I was like โokay every buoy, letโs put in an extra little dig and see if we can extend that leadโ. To come out of the water with a 90-second lead was more than I would have hoped for, I thought I might get a minute, but actually to have 90 seconds was a really nice amount of time.โ
The bike โ building the gap
โMy main focus out of the swim was just to be smooth through the transition which I was happy that I did that, and then just obviously get away on the bike and try and establish as much of a gap as I could in that early part of the bike.
โThe cool thing about the course was that there was an out-and-back very early on to the bike course, so straight away then I could work out what the gap was to the other girls and it was over a minute very early on. It was โokay, Iโve had a good swim, letโs try to keep pushing that pace upโ.

โAt the halfway point on the bike there was another out-and-back, and at that point I think Iโd grown the lead over Daniela and Taylor to like three minutes. So I was like โokay this is going pretty well, this is probably going better than I thought it wouldโ.
No power, no problem
โOne of the things that I did differently on this race, Iโd had some issue with the pairing of my power meter to my bike computer. So we decided that I would just race with no heart rate and no power, and just do it totally on feel.
โAnd actually I found it way better because sometimes if that data feedback isnโt what you want to hear and youโre looking at it and going โwhy I am only pushing that many watts or why is my heart rate so highโ, it can definitely put you into a slightly negative mindset.
โSo I was like โactually this is better, I feel good, Iโm kind of getting a feeling the gapโs getting biggerโ and all Iโm looking at and focusing on is how fast Iโm going and how long Iโve been riding, making sure Iโm fuelling properly. So actually I thought that was a lot better, and obviously when youโre having a good day that keeps your head completely in a positive place.โ
The run โ silencing the doubters
โComing off the bike I think I had a nearly six-minute lead, I was pretty confident in my run ability. I knew the course itself was gonna suit me because it was a hilly course โ I enjoy running hils in my training. I felt like it was almost, as long as I didnโt make a mistake on that run, it was a half-marathon run to go and finally claim a world title.

โThere was so much fire there just to prove that (running ability). I remember, I think it was 2016, I went and ran a 1:21 half-marathon on a really hilly course in Watford. So even back then I was like โI know I can runโ. I always ran for school and my swim fitness helped me run well.
โI think I would have actually been annoyed if I hadnโt delivered the fastest run split. I just wanted no question marks there, I wanted to be the most dominant athlete on the course. Obviously you have no idea what anybody behind you is doing, so Iโm obviously like โIโm just gonna run my own raceโ, but then at the end to find out that I was the fastest on all three disciplines, I guess for once in my life I felt like nobody could question anything that Iโd done.
โI feel like always something has been pulled apart of a race that Iโve done. So to be finally like โyou canโt question anything Iโve done thereโ was very sweet for sure.โ

The fuelling โ rice and Red Bull
โLeading into the race I pretty much only ate rice for a week. I was nervous because of what had happened at the Collins Cup (suffering from a stomach bug). I just wanted to make sure my stomach behaved itself on race day. I remember, probably a day out from the race, just craving all foods and I was like โwell the faster I finish the race, the quicker I can get to the point where I can eat whatever wantโ, so that was a good motivator.
โIn terms of the race itself, I decided I would take a small gamble and not use any caffeine until I got to the run part of the race. In terms of fuelling for obviously the swim, just get through the swim. On the bike I was just using basic sugar and electrolytes just to fuel me โ I didnโt have any solid fuel. I actually didnโt have a huge amount of fuel on the bike, I feel I had just enough to get me through that bike, which was probably around 40 grams of carbs per hour, so itโs definitely way on the lower side than maybe what most people would have. But that got me to the run confident that I could have more.
โOn the run we were very lucky to have Pro aid stations which were at 5k and 15k into the run. So on those aid stations I basically had like a Red Bull sugar mix which I was like โthatโs gonna give me that little extra boostโ because I hadnโt had any caffeine up until to that point and that definitely did work really really well. Other than that I was just using the aid stations on the course for some water.
โSo it was kind of a very basic fuelling strategy, but it felt like it was just enough on the day. The weather could have been a lot hotter, but it actually wasnโt too hot so I felt like hydration wise I didnโt need a huge amount either.โ
