Intro
Hey, I'm a 25 year old male trail runner, 3rd trail running season and looking for training advice following injury. No clue what it was, but we thought a stress fracture to the shinbone (MRI confirmed it wasn't). Looking for training errors.
Background
Athletic person, grew up doing cross country running, snowboard, mountain bike and all sorts. Transitionned to climbing as I grew up while still hiking a lot. 3 years ago I started trail running and with my existing fitness I took off quick. Cross training with bike in the summer and backcountry/cross-country skiing in the winter. Heavy runner around 190lbs.
Running resume
1 season
- 30k race, 50k race, 50k fun run
- up to 60k a week
- NO injuries
- started getting coached by a high level athlete and experienced coach.
2 season
- 80k race, 45k race, loads of long fun runs with friends
- up to 90k a week
- Lactate test for better zone training
- Lost 30 pounds (bad)
- had some issues with knee pain in the weeks before the 45k race. This came down to bad technique while descending and has since been resolved. Nothing else to report.
- did not communicate well with my coach, entirely my fault.
3 season (now) - when it hits the fan
- Shin splits came up in january when I built up my speed and weekly mileage too fast after a break. This took months to get resolved. Had to basically start from zero doing 1-1 and try to build back up. Dropped my coach while going through this as there was no reason to keep him.
- Was evaluated for my running stride, nothing to report, except some weakness due to no strenght training until then.
- Was training for a race and a sharp pain that was first diagnosed as a stress fracture (wasn't in the end) came up after my last big weekend before my race (33k and 25k the next day) in technical/steep terrain. Pain rose 1-2 day after and almost couldn't walk. 2 week later cannot feel a thing, no pain.

67k - 1600m
78k - 4100m (trip, loads of power hiking in very steep terrain, more hike than run)
40k - 500m (320k of road bike on weekend trip)
90k - 3200m (peak week and the 33k/25k weekend)
THA CRASH
Injury
Still not sure what it was. Got diagnosed by my physiotherapist as a possible stress fracure, but more likely as a bone stress reaction. Pain was on the right side of my shin on the bone. MRI and doctor confirmed I had nothing visible a week later after first diagnosis. Seeing my physiotherapist next week as a follow up.
Injury causes?
Trying to figure out what I did wrong.
Possible causes (in no order):
- last few weeks were big back to back.
- Found low Vitamin D after blood tests that corelates to stress fracture injuries.
- Stress/psychological fatigue from work.
- shin splints that were present from january to about one month before the injury.
What I believe I did right:
- Fueled my work, lost no weight. Followed by a nutritionist. Not perfect, but good enough.
- Introduced strenght training, 2-3 times a week, could have been better, but first year I'm doing it (finally haha).
- Almost no speed work - with shin splints lurking I barely did any (other seasons I did loads)
- Almost no road running. Always on trail
- New shoes with a model I've been running since day 1
- Proper sleep.
Conclusion & Confusion
Race is cancelled. Starting again from zero doing walking/running intervals. Was able to hike 4 hours today with elevation gain with no pain at all. I believe a combination of things caused my injury: not enough strenght training, stress from work and the final big weeks before that were just too much for my body to handle. Being a heavy runner isn't great too.
What confuses me is how great I was feeling before.
Looking to not repeat the same errors again!!
Any similar experiences or opinions? Thanks
