Coaches Brian Rosetti of V.O2 and Jeff Gaudette of RunnersConnect share key elements like mileage, workouts, and recovery. The article draws on a recent Sports Medicine study and appears amid rising interest in fast marathon times.[[1]](https://www.runnersworld.com/training/a70855896/how-to-run-sub-3-marathon/)\n\n## Key points\n- Build mileage gradually to **45-60 miles per week**; fastest marathoners averaged **62+ miles**, over three times slower finishers' **28 miles**.[[1]](https://www.runnersworld.com/training/a70855896/how-to-run-sub-3-marathon/)\n- Prioritize easy-paced miles for volume; moderate and hard efforts stay similar across ability levels.\n- Fuel with carbs on every run, especially longs, to boost recovery and gut adaptation for race day.\n- Do 2-3 quality sessions weekly: marathon-specific threshold runs like **2x5-6 miles at marathon pace** or **8-mile tempo** (5 at MP, 3 faster).[[1]](https://www.runnersworld.com/training/a70855896/how-to-run-sub-3-marathon/)\n- Mix threshold and marathon pace in workouts, e.g., 5MP +1 threshold +4MP +1 threshold +1MP, about 6 times per cycle.\n- Strength train 2-3 times weekly with functional core moves like hip dips over static planks.\n- Get bloodwork for B, D, iron levels when feeling good to optimize supplements.\n\n## Details and context\nStart from a recent marathon around **3:20**, not slower, and progress over multiple blocks; jumping from **40 to 60 miles** risks injury. A 2024 Sports Medicine study of over **119,000 runners** shows volume via easy miles separates elites.[[1]](https://www.runnersworld.com/training/a70855896/how-to-run-sub-3-marathon/)[[3]](https://runnersconnect.net/sub-3-marathon-training)\n\nThreshold work simulates late-race fatigue better than excess VO2 max or long runs alone. Functional strength builds running-specific power and resilience.\n\nMany runners undervalue fueling, recovery, and non-running factors despite high mileage.\n\n## Key quotes\n- “So many runners do have the ability to get there but just don’t do the right type of training.” —Brian Rosetti[[1]](https://www.runnersworld.com/training/a70855896/how-to-run-sub-3-marathon/)\n- “Marathon-specific work trumps any other type of speed session.” —Jeff Gaudette[[1]](https://www.runnersworld.com/training/a70855896/how-to-run-sub-3-marathon/)\n\n## Why it matters\nSub-3 remains a rare milestone, achieved by few finishers, but data shows more runners can reach it with targeted training. For dedicated amateurs, it means committing to higher volume, specific workouts, and holistic habits like fueling and strength. Watch personal progress over cycles and any new large-scale training studies for refinements.","hashtags":["#running","#marathon","#training","#fitness","#endurance","#sports"],"sources":[{"url":"https://www.runnersworld.com/training/a70855896/how-to-run-sub-3-marathon/","title":"Original article"},{"url":"https://runnersconnect.net/sub-3-marathon-training","title":""}],"viewCount":2,"publishedAt":"2026-04-13T18:14:37.563Z","createdAt":"2026-04-13T18:14:37.563Z","articlePublishedAt":"2026-03-26T20:00:31.000Z"}
