most plans are built around perfect weeks. you probably don't have many of those, and neither do i. work gets busy, travel happens, sleep suffers. so rather than handing you a rigid schedule and hoping for the best, i build training around the life you actually have. your programme will look different from someone else's. it should.
whether it's a 5k or a marathon, the goal is the same: holding the right pace for longer. controlled intensity, easy days that stay easy, and load managed carefully so every session earns its place.
this is where i've spent most of my own time. the trails ask for different things: climbing, descending, long hours on your feet. we train for the course you've entered, so your legs are ready for the race, not just the miles on the plan.
sportives, gran fondos and the big alpine days. long rides that build the engine without wrecking the week, and the climbing legs to enjoy the mountain rather than survive it.
three sports and a job is a scheduling problem before it's a fitness one. we set priorities so the sessions that matter get done, and the ones that don't get cut without guilt.
the plan is the starting point. the coaching is what happens after that.
thirty minutes. where you are, where you want to get to, what has got in the way before.
before the structured work starts, we find out where your fitness actually is and how your body handles load. no zones copied off the internet.
sessions go in ahead of time with suggested timings, and you fit them in where they work. some weeks that looks textbook. most weeks it doesn't, and that's fine.
a short catch up every week. if work has been rough, we dial it back. if a niggle shows up, we manage it. if you're flying, we push on. heart rate, pace and feel all tell me something, and the more honest you are, the better i can coach you.
someone who trains steadily for forty weeks will beat someone who goes all in for twelve and burns out. every time. getting the routine right isn't a compromise on results, it is the approach.
most people train too hard on easy days and not hard enough when it counts, and end up stuck in the middle: never fully recovering, never fully adapting. if your easy run feels embarrassingly slow, you're probably getting it right.
if you want to get faster, regular, controlled threshold work is the most effective thing you can do, week after week rather than smashing yourself occasionally. if you want to get round your first marathon or triathlon, that's a different job: volume and consistency matter more, and the priority is arriving at the start line healthy. the intensity matches the goal, not the ego.
sleep, easy days and rest weeks aren't rewards. they're how training actually works. skipping them doesn't make you tougher, it makes you slower and more likely to get hurt.
everyone should do some strength work. one or two short sessions a week makes a real difference to how robust you are. i'm a big believer in yoga too, as much for stress and staying consistent as for flexibility.
i play rugby, so triathlon was a bit of a leap. callum built things up gradually, kept me in one piece and got me round my first ironman. a good experience start to finish.

i wanted a faster marathon. callum sorted my easy days and my fuelling, and the plan fitted in around work without much fuss. pb in the half on the way through, then pb in the marathon.

i'm callum. i live in bern, switzerland, and coach people all over. i've got a full time job, so my own training happens around work: early mornings, lunchtime runs and long weekends, the same as most of the people i coach.
i started with road marathons, moved into triathlon, and then found my way to the long stuff. the ironman world championships in kona, the tour du mont blanc on the bike, and 121km at the helvetia backyard ultra before it beat me. running and cycling aren't just what i coach, they're part of how i live day to day, and i'm still training and racing myself.
along the way i've made most of the mistakes i now stop my athletes from making: too much too soon, riding through knee pain, fuelling on vibes. i read the research so you don't have to, and i'll tell you plainly when something's marketing rather than science.
that's fine. plenty of people start with "i want to run without breaking" or "i want to get fit enough to pick a race". we'll build the base, and the race will suggest itself.
this is a lot of my coaching. we start with what you can do today, not what you could do last year, and build back up under control. i'm not a doctor or a physio though, so if something needs professional attention i'll tell you.
doesn't matter. i don't care about your pace, your history or where you're starting from. effort, not perfection, and honesty about how things are going. that's all i need.
slower than you'd like, quicker than you'd fear. fitness is built over months, and anyone promising more than that is selling something.
monthly, cancel any time. ask on the intro call and i'll give you a straight number.
no pitch, no pressure. tell me where you are and where you want to get to, and i'll tell you honestly whether i can help.
