Return to run
Come back from injury without re-injuring
Most re-injuries happen in the first 6 weeks back. The single biggest cause is ramping volume too fast — ignoring the ACWR safe zone of 0.8–1.3. Pick your injury for an evidence-based return plan, or use the calculator below for a generic safe ramp.
Stress fracture
Bone needs to remodel. Walking → walk-run → easy run progression with pain-free criteria at each stage. The most unforgiving running injury for athletes who rush.
Runner's knee (patellofemoral pain)
Most common running injury. Usually no full layoff needed — load reduction plus quad and glute medius strength. Return-to-run criteria: pain-free walking + squat.
Plantar fasciitis
Foot heel pain, worst in the morning. Eccentric calf raises, plantar fascia stretching, supportive shoes. Most don't need full layoff — pain-monitored running can continue.
IT band syndrome
Sharp pain on the outside of the knee, worst on downhills. Stop running until pain-free, then return. Glute medius strength is the long-term fix.
ACWR safe-return calculator
If you don't know your injury or you're returning from a non-specific layoff (illness, travel, life), this is the generic safe ramp. It respects the ACWR ≤ 1.3 ceiling and ramps 10% per week.
停跑一段时间后重新开跑，是运动员最容易二次受伤的时刻。ACWR（急性:慢性负荷比）模型把每周负荷压在 1.3 这个受伤风险阈值以下。填入你的数据 — 我们会生成一份保守的 8 周渐进计划。
停跑之前你每周跑的量。
包括你停跑的那一周。本周跑过就填 0。
你的 8 周回归计划
只用轻松配速跑。每次跑前跑后都走 5 分钟。如果跑中或跑后疼痛加重，就重复上一周 — 不要往前推进。
| 周次 | 总 km | 每次跑量 | 备注 |
|---|---|---|---|
| 1 | 8 km | 2 km/次 | 走跑交替；非常保守。 |
| 2 | 9 km | 2 km/次 | 走跑交替；非常保守。 |
| 3 | 10 km | 2 km/次 | 连续的轻松跑。 |
| 4 | 11 km | 3 km/次 | 连续的轻松跑。 |
| 5 | 12 km | 3 km/次 | 接近受伤前的负荷。 |
| 6 | 13 km | 3 km/次 | 接近受伤前的负荷。 |
| 7 | 14 km | 4 km/次 | 接近受伤前的负荷。 |
| 8 | 16 km | 4 km/次 | 接近受伤前的负荷。 |
这份计划遵守 ACWR ≤ 1.3 的上限。如果你涨得比这更快，已发表的文献显示再次受伤的风险会翻倍。
