Design outcomes

Primary

Measure	Time frame
Medial meniscus extrusion over time, measured at baseline, before and after each stage as well as at the 2-week follow-up after the end of the race, determined by ultrasound as the difference in millimeters between the supine and standing positions.	—

Secondary

Measure	Time frame
1. Change in knee pain scores, measured at baseline, before and after each stage, and at follow-up 2 weeks after the race, assessed using the visual analog scale (VAS) 2. Changes in knee condition, measured at baseline and follow-up, assessed using the patient-reported outcome measures (PROMs) Tegner Activity Index and KOOS Score 3. Absolute medial and lateral meniscal extrusion, measured at baseline, before and after each stage, and at follow-up 2 weeks after the race, determined by ultrasound as the difference in millimeters between the supine and standing positions	—
