Hansons Marathon Method.
The Hansons Marathon Method, developed by brothers Keith and Kevin Hanson, is built on a single radical idea: your long run should never exceed 16 miles (26 km). Instead of a single 20+ mile run that requires days of recovery, the Hansons method accumulates fatigue across the week so that every long run is performed on tired legs — simulating the last 10 miles of the marathon without the injury risk of ultra-long training runs.
Philosophy and origin
Keith and Kevin Hanson founded the Hansons-Brooks Distance Project, one of America's most successful post-collegiate professional training groups, producing multiple Olympic Trials qualifiers and national-class marathoners. Their method was born from a practical observation: recreational runners who built their entire training week around a single 20-22 mile long run often broke down with injury, required 7-14 days of recovery that compromised subsequent training quality, or simply stagnated. The cumulative fatigue model was the solution — distribute the fatigue across the week so the long run simulates late-race conditions without the recovery cost of an ultra-long single session.
Cumulative fatigue model
Instead of one dominant long run, the Hansons weekly schedule deliberately packs quality sessions (tempo runs and intervals) in the days before the long run. By the time you reach your 16-mile run on Sunday, your legs carry the accumulated fatigue of 60-80 km of prior running that week — including a hard interval session and a threshold tempo run. You are effectively running the last 16 miles of a marathon, not the first 16. This fatigue-state simulation is the method's theoretical foundation: it teaches your body and mind to perform on tired legs without the injury risk and recovery burden of a 20+ mile training run.
Long run cap
The 16-mile (26 km) cap is the Hansons method's most distinctive and controversial feature. The Hansons argue, supported by their coaching data, that a 20+ mile training run takes 7-14 days to fully recover from — destroying the quality of every session that follows and creating a boom-bust cycle in the training week. The capped long run preserves week-over-week consistency, allows higher total weekly mileage, and maintains the quality of interval and tempo sessions throughout the training cycle. The cumulative fatigue from the full week provides the endurance stimulus without the single-session trauma.
Key workouts
Tuesday: VO2max intervals targeting maximum oxygen uptake — 6x1 mile at I-pace or 12x800m with 400m jog recovery. Thursday: tempo run at marathon goal pace — starting at 8 km and building progressively to 16 km over the training cycle. Sunday: long run at easy pace (22-26 km), performed on legs fatigued from the week's prior training. The remaining three running days are easy recovery runs of 30-50 minutes at conversational pace. One rest day per week (typically Friday). Total weekly volume builds progressively to 90-100 km for intermediate runners.
Who it suits
Marathon-focused runners at intermediate level and above who can commit to 6 running days per week and who trust the cumulative fatigue model's unconventional approach. Requires the discipline to run easy days truly easy (not moderate) so that quality sessions remain high-quality. Not ideal for 5K or 10K specialists, runners who prefer 3-4 day per week programmes, or beginners without a base of at least 40 km/week. Best suited for competitive recreational marathoners targeting specific time goals.
How STRIDD builds it
Select Hansons in the Architect and enter your goal marathon time. STRIDD calibrates your marathon-pace tempo, VO2max interval and easy recovery paces using Riegel prediction and VDOT tables, then builds an 18-week plan with the characteristic cumulative fatigue loading pattern and 16-mile long run cap. Volume ramps progressively from 50 km/week to peak mileage, with built-in recovery weeks (20% volume reduction) every fourth week to allow adaptation and prevent overtraining.
