Michael, better known as SupaDupa Slim, is a 2:15 marathoner from Austin, Texas, coached by Jeff Cunningham of Bat City Track Lab. His path to 2:15 has been anything but linear: from the slow kid on the team in a small Texas town, to a marathon that fell apart in the second half, to missing the Olympic Trials standard by seconds, and finally to running 2:15 at the McCurdy Pro Marathon and qualifying.

In this conversation, Michael breaks down what actually moved the needle: small, steady jumps instead of big leaps, a smarter approach to mileage, learning to run marathon pace without fear, and why time alone should never define you as a runner. He walks through his training week for the marathon, the block behind the 2:15, and the race itself. He also explains where the SupaDupa Slim name comes from.

Before the interview, Kristian shares his own training update on the road to a sub-2:30 attempt in Valencia, including a 3:21 per kilometer opener in a session he did not expect to hold.

In this episode:

• Where the name SupaDupa Slim comes from
• From slow kid to 2:15 marathoner, 25 years of running
• Two first marathons and what they taught him
• Overtraining, injury and rebuilding with patience
• Why small jumps and consistency beat big leaps
• How to chase a faster pace without freezing up
• A full marathon training week and the block behind the 2:15
• His mileage philosophy and advice for runners
• The McCurdy Pro Marathon, mile by mile
• Next up: the Houston Half Marathon and a Boston pro field hope
