Soft tissue care during marathon training

How marathon training loads the body

A standard 16-week marathon plan increases weekly mileage from a base of 25–30 miles to a peak of 50–60 miles. The tissue damage accumulates with mileage, particularly in the calf-Achilles complex, the patellar and quadriceps tendons, the IT band region, and the plantar fascia.

The training plan is the stimulus. The soft tissue maintenance is what determines whether the stimulus produces adaptation or injury.

Weeks 1–4: establish tissue baseline

An assessment at the start of the training block identifies existing restrictions before they become injuries. A tight calf that is present at week 1 will be a symptomatic calf strain by week 8 if mileage increases unchecked. A clinical assessment early is prevention.

Sessions during this phase: fortnightly. Soft tissue work to the posterior chain, hip flexors, and any identified restrictions. No urgent problems, maintenance mode.

Weeks 5–10: high volume phase

As weekly mileage increases beyond 40 miles, tissue accumulation accelerates. Session frequency should increase to weekly if the athlete has a history of overuse injury, or every 10–14 days for lower-risk athletes.

Primary targets in this phase: calf complex and Achilles (absorbing the increasing mileage load), IT band region and TFL (high volume running increases lateral hip tension), and lower back and gluteal complex (fatigue-related gait changes increase posterior chain load toward the end of long runs).

Weeks 5–10 are where most marathon injuries begin. Not because the mileage is highest, because the accumulated load is highest.

Peak weeks and taper

Peak mileage weeks (typically weeks 12–14) warrant a session within 48 hours of the long run, the highest cumulative load of the training block. The taper (weeks 14–16) reduces training load and allows tissue recovery before race day. One session in the taper week, 5–7 days before the race, is appropriate. Not the day before.
