ULTRA SCIENCE
Returning to running after a problem
Resume according to the problem and your response, not a universal calendar.
The decision
What should be established before I rebuild running after an injury?
Establish the starting point
After suspected bone stress, obtain clinical assessment before impact progression. Location and severity change management; absence of pain alone does not prove healing.
Use criteria, not deadlines
Clinicians consider daily function, pain-free loading and injury findings. Agree on activity limits and reassessment criteria. Return to easy running and return to ultra racing are separate decisions.
Review the response
Record symptoms during activity and afterwards. Recurrence means reassess, not automatically advance. No universal weekly percentage or fixed pain allowance fits every tissue problem.
Check the wider context
Repeated bone problems or prolonged underfueling justify discussion with a clinician and sports dietitian. REDs affects women and men; this page cannot diagnose it.
Create a return agreement
Before the first running session, write down four things with your treating professional when relevant: what you are returning from, what has been cleared, what remains restricted, and what triggers reassessment. Be specific about the task. Permission for short easy running is not permission for technical descending, speed work or a race. Ask how to handle a flare-up and who to contact. If the diagnosis or restrictions are unclear, resolve that uncertainty before designing progression around a race date. This agreement is an organizational aid, not a substitute for clinical clearance.
Keep a simple return log
For each planned exposure, record the agreed activity, its actual duration, route and effort, symptoms during it, and the later response. Include relevant daily activities: an unusually demanding workday or hike can make the running entry alone misleading. At the next review, choose explicitly between repeating, progressing, reducing or seeking reassessment. Do not add missed training automatically to later sessions. The log is useful because it preserves context for decisions, not because it calculates when tissue is healed. There is no validated universal score produced by this worksheet.
Separate return goals
Use distinct questions: Can I manage ordinary daily activity? Can I tolerate the agreed easy-running task? Can I repeat it? Am I ready for the additional demands of my event? The answers may differ. Trail terrain, descent, accumulated fatigue and carrying equipment are separate demands to discuss and rehearse after the basic return is established. A calendar can organize reviews, but it cannot make these decisions for you. Racing while still negotiating basic running tolerance changes the risk discussion and belongs in the conversation with the professional supporting your return.
Questions for the next review
Bring the return log and describe the activity you want to add next. Ask whether that specific change fits the assessed problem. If there was a setback, identify what actually happened rather than calling the whole return a failure: was the task longer, faster, steeper or simply different? Did symptoms return during the session or later? Was ordinary walking affected? A professional can interpret these observations within the diagnosis. The page cannot. Agree on the next action and the circumstances in which the plan changes. If running is restricted, ask about permitted alternatives instead of assuming cycling, hiking or strength exercise is automatically suitable. Preserve the distinction between maintaining general activity, completing rehabilitation and preparing for a particular race. A useful return plan names those goals separately and makes uncertainty visible.

Evidence and limits
Evidence: Mixed. Clinically relevant across sports; not an ultra rehabilitation trial. Consensus includes uncertainty and is not a universally validated return schedule.
Version and review
AI-assisted evidence appraisal is not credentialed clinical review. Publication authorization and application release dates are separate from scientific review.
Evidence markers identify statements and their limits; practical examples are not validated individual prescriptions.
