You're a person, not a plan.
Ultra Endurant is run by me, Jonathan Fors — a UESCA-certified coach with years of lived experience behind the certificate. There are plenty of coaches out there. Few of them see a person as a whole person with a life to live.
Most plans start with the schedule and expect your life to bend around it. I start at the other end. Your work, your family, the worries you're already carrying — all of it changes how your body handles training, so all of it gets counted before a single session is written. Rest, and everything else off the road, is part of the work rather than a gap in it.
I know what the other way costs. I've run 744 km down the coast of Portugal, and I've stopped at 480 km on the same route two years earlier because my body had had enough of being overruled. The second one is the line on the page. The first one is the reason any of this is worth listening to.
A week you can repeat is worth more than a perfect week you manage once. That's the whole method. Everything else is detail.

UESCA-certified · Ultra Coach
Every single athlete works directly with Jonathan. No sub-contractors, no outsourced assistants.
Science-first.Life-adjusted.
Training science sets the direction. Your life sets the constraints. Your plan is written where the two meet — and rewritten every time life moves.
What the science says
The proven stuff works.
- Periodized blocks that build toward your race date
- Proven fuelling and pacing targets, not guesswork
- Progressive load with planned recovery weeks
- Strength, mobility and durability work that keeps you running
What your life says
But you don't live in a lab.
- Shift work, kids, travel and weeks that fall apart
- Niggles, bad sleep and days you're just flat
- Races that matter and races that are just for fun
- Motivation that comes and goes — because you're human
Your plan livesin the middle.
Evidence over trends
No fads, no miracle sessions. The methods are the ones with decades of research and finish lines behind them.
Adaptation over guilt
A missed session isn't a failure — it's data. The plan reshapes around your week instead of punishing you for it.
Consistency over hero weeks
Ultras are finished by runners who stack ordinary weeks for months, not by one perfect block.

“The best plan isn't the perfect one — it's the one you can actually live with for months.” That's why every adjustment starts with what's happening in your life, not just your splits.
Showing up is the hard part.
Most runners don't fail from a bad plan. They drift. A busy week, a niggle, a missed long run — and nobody notices. Here, somebody always does.
