For many UK runners, mid-March marks a noticeable shift. The days are lengthening, the air feels less biting, and training plans begin to demand more: longer Sunday runs, midweek tempo sessions, perhaps a tune-up race at the weekend. After months of steady base-building through winter, the sudden increase in volume and intensity can feel invigorating – until the feet start to protest. A dull ache in the heel after a hilly effort, tenderness under the ball of the foot during strides, or a general sense of fatigue that lingers longer than expected. These are familiar signals as mileage climbs toward spring targets such as the London Marathon, local half marathons or early-season trail events.

The transition from winter maintenance to spring preparation places new stresses on the feet. Harder surfaces after softer, muddy trails, combined with faster paces and greater weekly distance, can amplify repetitive impact. The plantar fascia tightens with the added load, metatarsal heads bear more pressure during quicker turnover, and small muscles that stabilised slower winter runs now work overtime to control motion. Without attentive care, these changes can quietly escalate from discomfort to disruption, derailing weeks of carefully laid plans.

Runners who navigate this phase successfully tend to prioritise prevention alongside progression. They continue the drying routine established over winter – ensuring shoes never remain damp overnight, as residual moisture softens skin and heightens friction during longer efforts. They introduce or maintain taping on vulnerable areas during key sessions, allowing the feet to adapt gradually to increased demands. Shoe rotation remains essential: alternating pairs prevents overuse of any single midsole and keeps one set consistently fresh. Gentle mobility work – calf stretches, toe yoga, ankle circles – helps maintain flexibility as loads rise.

Practical measures for the mileage build

• Dry footwear thoroughly after every run. Rapid internal drying preserves skin integrity.

• Apply tape proactively to toes or heels on longer or faster days.

• Rotate at least two pairs of trainers to distribute wear and maintain dryness.

• Incorporate short foot-strengthening exercises two or three times a week.

The ramp-up to spring racing is a period of exciting progress. Handle the feet with the same thoughtfulness given to pace and nutrition, and the increased mileage becomes sustainable rather than punishing. The longer runs feel stronger, recovery quicker, and race-day confidence builds steadily.
