Return to Running After an Ankle Sprain: A Week-by-Week Guide

Ankle sprains are one of the most common injuries we see in runners, and one of the most mismanaged. Many people either rest too long out of caution, or go back too soon because the pain has settled and the swelling has gone down. Neither approach serves you well. The ligaments on the outside of the ankle heal on a fairly predictable timeline, but the balance, strength and control around the joint often lag well behind how it feels day to day — which is exactly why re-sprains are so common in the first few months after the original injury.

This guide gives you a general week-by-week framework. It assumes a typical mild-to-moderate lateral ankle sprain (a roll or twist, some swelling and bruising, difficulty weight-bearing for a day or two). If you heard or felt a pop, couldn't put any weight on it at all, or things aren't improving as expected, it's worth getting it properly assessed rather than guessing.

Week 1–2: Calm it down, keep it moving

The old advice was total rest. We now know that gentle, pain-guided movement heals ligaments better than immobilisation. In the first fortnight, the goals are to reduce swelling, protect the ankle from further rolling, and restore normal walking.

• Move the ankle through pain-free range several times a day — gentle circles, pointing and flexing.
• Weight-bear as much as comfort allows; use crutches only if you genuinely can't put weight through it.
• Ice and elevation help in the first 48–72 hours if swelling is significant.
• Start basic balance work as soon as standing is comfortable — even just standing on the injured leg while brushing your teeth.

Running is off the table here. The ligament is still in its early repair phase and needs protection, not load.

Week 3–4: Rebuild strength and balance

Once you can walk normally without a limp, the focus shifts to strength and proprioception — your ankle's sense of where it is in space, which is often the last thing to recover and the biggest factor in re-injury risk.

• Calf raises, both double and single leg, building up reps and control.
• Resistance band work for the muscles that evert the ankle (turn the sole outward), since these are often weak after a lateral sprain and are your main defence against rolling it again.
• Single-leg balance progressions: eyes open on a firm surface, then eyes closed, then on a cushion or wobble board.
• Light hopping in place once single-leg balance feels solid.

This is a good stage to have things checked by a physio if progress feels slow or uncertain — a structured strength and conditioning programme tailored to your ankle can shortcut a lot of trial and error, and catch any lingering weakness before you start adding running load on top of it.

Week 4–6: Introduce running, gradually

Before your first run, you should be able to walk briskly and pain-free, perform 20+ single-leg calf raises, hop on the spot without pain, and balance on one leg for 30 seconds with your eyes closed. If any of these aren't there yet, give it another week rather than pushing through.

• Start with a run-walk protocol on flat, even ground — for example, 1 minute running, 1 minute walking, repeated for 15–20 minutes.
• Choose predictable surfaces early on. Save trails, grass and uneven pavements for later, once your balance reactions are quicker.
• Increase running time before you increase pace. Speed and direction changes place far more demand on the ankle ligaments than steady, straight-line running.
• Expect some mild ache or stiffness after a session — that's normal tissue adaptation. Sharp pain, giving way, or swelling that returns is a sign to scale back.

Week 6–8: Build volume and add variety

By now most people are running comfortably at an easy pace. This stage is about closing the gap back to your normal training — increasing distance by no more than around 10% a week, and slowly reintroducing the things that actually cause re-sprains: hills, uneven terrain, faster efforts, and change-of-direction sports if that's your thing.

• Add gentle hill running and light agility drills (side-steps, figure-of-eights) once flat running feels effortless.
• Keep your balance and eversion strength work going in the background — it's easy to drop once running feels fine, but this is what protects the ankle under fatigue, which is when most re-sprains happen.
• If you're training towards a specific race or event, this is a sensible point to have a professional review your marathon or running preparation plan, so your ankle rehab and your training build are working together rather than in conflict.

When to get it checked

Most straightforward sprains follow this kind of timeline reasonably well. But if pain persists beyond a few weeks, the ankle keeps swelling after activity, it feels unstable or gives way, or you're not confident about how hard to push, it's worth having it assessed properly rather than guessing your way through it. A thorough physiotherapy assessment can identify whether there's residual ligament laxity, a strength deficit that needs targeted work, or something else going on that a generic guide won't catch.
