⏱️
Pacing Precision
Pacing discipline is the ultimate predictor of half marathon success. Runners who keep their splits even finish an average of 27 to 34 minutes faster. Our AI precisely calibrates your training paces to ensure perfect execution.
🧱
Predict & Prevent the Wall
While less common than the full marathon, late-race slowdowns still plague many runners (men are twice as likely to hit the wall). TrainAsONE analyses your patterns to identify pacing risks early and keep your second half strong.
🏃♀️
Join the Biggest Field
The half marathon is the world's most popular distance, boasting over 2.1 million annual participants. It's also a massive draw for female runners, seeing over 12 times the number of female participants compared to the full marathon.
🩺
Beat the Attrition Rate
Up to 16% of half marathon registrants end up as a DNS or DNF, largely due to training errors. By constantly monitoring your acute and chronic loads, we optimise your schedule to get you to the start line healthy and ready to perform.
🏅
The Sub-2:00 Benchmark
Breaking two hours is a hallmark goal, placing you in the top 45% of all runners (and the top 25% for women). TrainAsONE dynamically adapts to your specific fitness level to help you smash those elusive time milestones.
🔋

Half marathon training is the ultimate "fitness hack" - providing roughly 90% of the cardiovascular benefits of full marathon training while causing only 50% of the physiological damage and muscle strain. Train smart, recover faster.
