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 fromFrom slow kid to 2:15 marathoner, 25 years of runningTwo first marathons and what they taught himOvertraining, injury and rebuilding with patienceWhy small jumps and consistency beat big leapsHow to chase a faster pace without freezing upA full marathon training week and the block behind the 2:15His mileage philosophy and advice for runnersThe McCurdy Pro Marathon, mile by mileNext up: the Houston Half Marathon and a Boston pro field hopeTimestamps 00:00 Introducing Michael 01:44 Kristian’s training update 02:08 Saysky 14:45 Interview begins 14:52 The name SupaDupa Slim 16:52 What running means to Michael 20:03 Staying consistent for 25 years 22:32 Growing up with running siblings 26:40 His first marathons 32:43 Learning what it takes 39:01 Injury and rebuilding 41:00 Time goals and the ceilings we create 44:53 Learning to run faster paces 48:17 Commitment and decision making 51:07 Coach Jeff Cunningham 53:32 A marathon block for 2:15 1:00:12 Recovery and fueling 1:03:49 Small habits and mobility 1:06:23 Mileage advice 1:10:23 Doing less and feeling better 1:13:24 A week of marathon training 1:17:45 The McCurdy Pro Marathon 1:23:06 Qualifying, emotions and the finish 1:26:11 What’s next 1:27:34 Wrap upMichael on Instagram: @supadupaslimStart your free Musicbed trial: https://fm.pxf.io/kristianwarwickFull episodes + the Boston 2025 documentary: https://www.youtube.com/@Warwickruns Follow my training journey on Instagram: @warwick.runs Music from Musicbed: MB01XPYH8ZYENVAMB0133EV2TCQFZY
