Data with a purpose
I love the numbers — power, pace, heart rate, sleep, HRV, load. But data only matters when it changes a decision. Every metric I track exists to answer one question: what should this week look like?
About JL
I started out coaching myself — building my own plans, chasing my own races, and learning the hard way what works and what just makes you tired.
I did all of this while working offshore and being a parent to my 11-year-old son, so I understand what it means to fit training around a demanding schedule, disrupted sleep and real-life chaos. I am proof that you can build fitness, race well and keep the important parts of life in place when the plan is built around the hours you actually have.
Then a friend asked for help getting to a 70.3. I said yes without really thinking about it, and somewhere in that build I fell in love with the process: the planning, the problem solving, the moment training clicks and someone realises they're capable of more than they thought. Seeing them cross that finish line changed things for me.
I've pursued coaching as a career ever since. JL Performance Labs is the result — a one-to-one coaching setup for triathletes, 70.3 and Ironman athletes, built on data, honest conversation and a plan that fits the life you actually have.
What I believe
I love the numbers — power, pace, heart rate, sleep, HRV, load. But data only matters when it changes a decision. Every metric I track exists to answer one question: what should this week look like?
Adaptation happens between the sessions. I plan recovery as deliberately as intervals, and I use your check-ins to spot the drift before it becomes an injury or a burnout block.
Long-course racing is decided as much in your head as in your legs. We work on pacing discipline, dealing with bad patches, and building the confidence that comes from having rehearsed the hard bits.
I'm not interested in copying a template. I keep testing new ways to structure blocks, present feedback and push athletes — then keep what actually works for you.
Think we'd work well together?
Tell me your goals, your race calendar and the hours you have. I'll tell you honestly whether I'm the right coach for it.
