A Junior Stress Fracture, a Selection Deadline and a Club Under Pressure

An athlete you coach is a 17-year-old female junior national squad member. She sustained a second metatarsal stress fracture 8 weeks ago; walking is pain-free but she has not run. She has had two stress fractures in 18 months, a BMI of 17.8, and irregular periods since age 15. Her parents and the athlete want her to race the national junior draft-legal championship in 3 weeks, and they ask you to sign her off as fit. She also takes a 'natural energy' supplement given by a friend, and the label lists a proprietary blend. She is 5 weeks into a 12-week school term with exams starting in 2 weeks. She is 16 weeks out from a planned international race and wants to keep her selection chances. The club director is pressuring you because the team needs her points.

1. Do you clear her to race? Justify your decision.

No. A second metatarsal stress fracture at 8 weeks with no running yet is not ready for draft-legal junior racing, which involves repeated accelerations, standing starts and unpredictable pack riding. The bigger red flags are the second stress fracture in 18 months, BMI 17.8 and irregular periods since age 15-a pattern consistent with low energy availability/RED-S and impaired bone health. A coach cannot medically clear a fracture; that requires a sports physician with imaging and bone-health assessment. Clearing her would risk re-fracture, prolonged loss of selection chances and long-term endocrine and bone harm. The club's need for points is not a medical indication. Document the decision, recommend urgent medical review, and offer a non-racing role at the event if appropriate. If she or her parents insist, explain that you will not sign the clearance and why.

2. How do you handle the conversations with the athlete, parents and club director?

Read the worked answer

Start with the athlete alone: ask what she understands, acknowledge her goal, and explain that the decision protects her career rather than punishing her. Use plain language: the bone is not healed enough for sprinting and pack riding; the repeated fractures and missed periods suggest her body is under-fuelled. Involve the parents in a joint meeting with consent, present the return-to-run criteria and the referral plan (sports medicine, dietitian, and endocrinology if appropriate). With the club director, keep it factual and confidential: 'She is not medically cleared; I will not sign. Here is the plan.' Do not share BMI or menstrual details beyond what is necessary. Put the decision in writing. Offer the club a replacement athlete and suggest the director speak with the medical professional if needed. Escalate to the safeguarding lead if pressure continues.

3. Set return-to-run and supplement guidance.

Return to running only with medical clearance and after pain-free walking, no bony tenderness, pain-free single-leg hopping and imaging confirmation of healing. Then use a walk-run progression: 1 minute run/2 minutes walk for 20-30 minutes, every other day, increasing run time by 5-10% per week if pain-free. No sprinting, hills or drafting for at least 4-6 weeks after starting. Address energy availability with a dietitian: adequate carbohydrate around training, protein 1.4-1.8 g/kg/day, and sufficient total energy; this is treatment, not a diet. For the supplement, a proprietary blend is a doping risk because ingredients may be undeclared or banned. Tell her to stop it, check every product on a reputable anti-doping database, and avoid anything not batch-tested. Discuss exam stress and sleep. Reassess in 2 weeks.
