Dear Performance Nutrition Leaders,
This week: SENr portfolio guidance, the latest performance nutrition industry moves, and Esteban Ocon’s travel strategy.
🧠 ON THE GROUND
A recent session inside the Performance Nutrition Network covered SENr portfolio submissions. The advice that stood out: make it blindingly obvious.
Hyperlinks, bold text, clear page references — make it as easy as possible for the assessor to find what they need.
One practitioner shared their own submission — 75 pages of supporting documentation. Screenshots of WhatsApp messages (names hidden). Meal plans sent to hotels. Supplement batch storage examples. A case study written as if it were going to be published — because it was. The assessor read it and told them to submit it to a journal.
The other insight: your evidence doesn't have to come from one place.
That portfolio pulled from multiple roles across football, rugby league, and boxing. "That shows you're a more rounded practitioner rather than a nutritionist for one sport."
And if you haven't done something? Say what you would do.
Assessors aren't just looking for proof you've done everything. They're looking for proof you know the process.
The takeaway for anyone building a credentialing system, a competency framework, or an assessment process: evidence defeats doubt.

Jet lag sucks.
For athletes, it doesn’t just suck—it steals wins.
Tom Clark, a performance coach, has spent four seasons managing Formula 1 driver Esteban Ocon’s travel strategy.
He knows the stakes: even one bad night of sleep can cost you.
The body clock operates on a rhythm just over 24 hours. Adjusting across time zones is all about precision.
Light is the secret weapon. Your body clock responds to light exposure—use it to either advance or delay your rhythm. If you know your core body temperature low (around 4 AM), light timing becomes a powerful tool.
Phaze App (by Tom Clark)
Jet lag vs. travel fatigue: Jet lag is a body clock misalignment. Travel fatigue is the wear from the journey itself. Understand the difference to tackle them better.
Tom’s advice: Eastward travel adjusts by one hour/day. Westward? Up to two hours/day. Long eastward trip? Treat it like a westward journey.
Actionable Takeaway:
Manipulate light exposure: Use light strategically to adjust your rhythm.
Plan sleep carefully: Shorten the gap between home sleep and destination sleep.
Avoid melatonin/sleep pills—they won’t fix your clock.
Tom has now turned this into a product: Phaze, an app that helps coaches and consultants personalise sleep and travel schedules using circadian science.
