Marc the Shark Hits it Out of the Park for 3rd at the IRONMAN 70.3 Gulf Coast

5/25/2026

🏊️ Swim:

Non-wetsuit, ocean swim, beach run-in. The chance for a truly honest swim that could get me and the good swimmers a big gap.

At the race briefing we were told that if, for some reason, we had more current, the plan was to shorten the swim to a 1000m point-to-point. I posed the question: “If it’s safe enough to get in the water for a 1000m swim, why is there not a plan to do a multiple lap course or out-and-back for the pros?”

It was heard, but not implemented.

I led to the first buoy and relaxed after that. Greg, Seth, and I all came out pretty much together and headed into T1 and out onto the bike in first place.

7:15 2nd fastest

Job done. ✅ 

🚲️ Bike:

I was very surprised to hear we had a 90 second gap to Sam after that swim. One-third of the swim and we still got 90 seconds.

Legs were feeling really good. Power was there right away and Seth and I got to work.

Around mile 22 (the first U-turn), I could see Sam was almost to us and Ari wasn’t much farther away. I knew a big move was coming once he got to us. I did my very best, but I was clearly overextending, so I settled back into my pace, still with really good numbers, and just held it there. 3 riders went up the road. 

I was still really happy with the last half.

Legs were decent at the end, but certainly feeling the completely flat course. I nailed the nutrition and got off the bike solidly in 4th.

Finished the bike not really knowing the gap, but eventually heard 2:30 down from the lead

1:53:17

4th fastest bike split on the day

326 avg / 332 NP

Job done. ✅ 

🏃‍♂️ Run:

2:40 down but feeling really good.

I was still surprised to see 3:13 and 3:16 pace for the first 2k. I wanted to go for it and give myself a chance.

I love 3-lap courses. For some reason they flow really well mentally for me.

I was on pace for around 1:08:50 through halfway but faded slightly on the back half.

Another really big step back toward where my run used to be, but this was off an even harder bike, so I guess it is back? 🤔 

"One is an instance, twice is a coincidence, three is consistency"

1:10:26
4th fastest run on the day

Job done ✅ Worlds spot 🌎️ 9th career IM podium 🏆️ 

-------------------------

If you made it this far, thank you. I really appreciate you following along.

Momentum is building.

Recovering now and getting right back to work.

T-minus 3 weeks until the IRONMAN 70.3 North American Championship.

The IRONMAN Pro Series made its way to North America, with fairer, faster racing that was not at all safer with the sketchy road conditions and fog that was so thick, it made descents turn into trust falls.
