Hi, I’m Shawn.

​

I built GritLab because of my mistakes, setbacks, and real performance pressure.

​

As a cyclist, I used to cramp around 60 km and couldn’t figure out why. It wasn’t fitness, it was mainly sodium loss for me. Fixing that changed everything. I went from struggling through rides to completing 300–400 km Audax without cramping.

​

Later, when I hit another plateau despite training hard on limited time, I realised something most cyclists miss:

​

It’s not a motivation problem.
It’s a bottleneck problem.

​

That led me deep into physiology — lactate testing, fueling, and performance diagnostics.

​

I applied that same approach in paracycling , analyzing race demands, competitors, and calculating the exact power and speed strategy needed to win. This resulted in a gold medal at the ASEAN Para-Games in 2025.

​​

Now, I help athletes who struggle in the heat stop guessing and start training based on what their body actually needs.

​

If you’re putting in the work but fading, cramping, or slowing down in the heat,
you’re probably not lacking effort. You’re solving the wrong problem.
