How I increased my FTP from 256W → 373W ⚡️

1. Ride consistently 🚂
3 rides/week for a year beats 6 rides/week for a month.
Consistency wins.

2. Increase your long ride 🚵‍♂️
Slowly build from ~2h → 4h.
Stay in Z2. Not harder. Not easier.
Keep pedaling as much as possible.

3. One hard workout per week 🔥
VO2max or threshold intervals.
These sessions should hurt. Fuel properly before them.
And sometimes… you should fail the workout.
If you never fail, you’re probably not pushing hard enough #ironman #triathletes #ironmantraining #ftptest #watts by @g_forstmann

IRONMAN 70.3 World Championships 2026 🇫🇷
Beautiful and brutal course. I loved every minute of it. Thank you to @sls3triathlon for the trisuit

🏊‍♂️ Swim: Definitely where I struggled the most. The non-wetsuit swim made it even harder, but I stayed patient and knew this wasn’t the place to try to be a hero.

🚴‍♂️ Bike: This course was made for me: hilly and technical. I must have passed 500+ people. My legs felt amazing and I felt like I was flying uphill and downhill. By the end of the bike, I was back in the top 50 of my age group.

🏃‍♂️ Run: I felt great for the first 5 km and held my target pace of 3:50/km, but then slowly started to fade. The heat on the Promenade des Anglais was intense. I had to dig deep to not explode. Kept my head down and pushed truth, survival mode.

Overall : I am happy with my result. 51st in my category (30-34) and 247th overall in the world (including pros) is not bad! I am excited to keep improving and hungry for what comes next 🔥Trained by @coachleon.ai taken in Nice Côte d'Azur by @g_forstmann
