The 5 Boston Qualifier Mistakes
Most Marathon Plans Make

A 28-year-old with no injury history and a 52-year-old with cranky Achilles do not need the same week. Generic plans don't know — and don't care — who is running them. BQ runners need a plan built for their age, history, and life.

Mileage alone doesn't create the speed reserves you need to hold BQ pace for 26.2. The qualifiers I coach do specific work at — and often faster than — goal pace. Easy miles don't teach your legs to race.

Sixteen weeks of training assumes sixteen perfect weeks. Real life isn't that. When you get sick, when work explodes, when a knee flares at week 8 — a real coaching relationship adjusts the plan that day, not next cycle. Generic plans force you to either push through and get hurt, or fall off entirely.

Finishing 26.2 and racing 26.2 at a specific pace under pressure are two different sports. BQ training means goal-pace intervals, fueling rehearsals, and segments at race pace on tired legs. Most plans skip this work entirely — and the runner pays for it in the final 10K.

Some courses give you a BQ. Some take it from you. Hilly courses, summer marathons, late-registration windows, qualifying cutoff math — race selection alone can be the 4 minutes between making it and missing it. Pick the course before you build the plan, not after.
