Post Ultra Mistakes That Nearly Set Me Back: My 15K Warning
Two weeks after finishing my first Ultra, I thought I was ready to start training again… until a “simple” 15K easy long run kicked me straight in the calf and stopped me in my tracks. Looking back, my recovery timeline was unrealistic, and I ignored the warning signs. So this video breaks down exactly what went wrong — and what I’ll be doing differently next time.
Post Ultra Week 1–2: The Signs Were There - Even though I said I felt good at the finish line, my body knew it had just gone through nearly 11 hours of effort. The first 48 hours were awkward but not painful — poor sleep, muscle ache, and that classic post Ultra stiffness. But I made my first mistake: I didn’t rehydrate or refuel properly. By day three I was already back out walking, and by the end of week one I was adding elevation again. Mistake number two.
The 15K Run That Went Wrong: By the end of week two, impatience took over. I wanted one last run in the Welsh mountains before heading back to the desert. At 10K, a brutal calf cramp hit — more like a strain than fatigue. I walked 2K, ran 3K, and finished the run knowing this wasn’t normal post Ultra tiredness. It was a warning.
Expert Advice That Changed Everything: Back in Abu Dhabi, I reached out to an experienced Ultra runner. His response matched everything I’d read but didn’t want to accept: Recovery should be 3–4 weeks before resuming structured training. Ultras cause deeper tissue damage, hormonal disruption, immune suppression — things you can’t “feel” but absolutely matter. Just because soreness fades doesn’t mean recovery is done.
What I Learned (The Hard Way):
Mistake 1: Returning to long runs too soon.
Mistake 2: Underestimating cumulative fatigue from prolonged time on feet.
Mistake 3: Ignoring the “silent” recovery systems.
Mistake 4: Letting the next race pressure override recovery logic.
I’ve always been good at pushing… not always good at pausing.
What’s Changing Going Forward: Recovery is ongoing until the end of August. Future Ultras will have a full 4 week recovery block before retraining:
Week 1: Rehydration, walking, mobility, sleep
Week 2: Walking with elevation + very easy short runs
Week 3: Light volume, no intensity
Week 4: Gradual return to structured easy training
Strength and mobility come before mileage. Fatigue markers (HRV, morning HR, sleep, mood) will be monitored — something I didn’t do this time.
Bottom line: Recovery is training.
I’m now moving to a 4 month cycle: 3 months training → race → 1 month recovery → repeat. I’m in this for the long run — not the one off race followed by injury.
If you’ve ever rushed back after a big race, you’re not alone. Your next race depends on how well you recover from the last one. Share your worst “too soon” comeback stories in the comments — I’d love to hear them.
