Everything you and your crew need

Built around your physiology

Carb tolerance, stomach profile, sweat rate, caffeine strategy — every plan reflects how your body actually works, not a generic athlete.

AI-powered plan editor

Edit your plan in plain English. "Add hot soup from loop 20" or "reduce carbs in the final phase" — the AI updates the table instantly.

Crew-ready output

Loop-by-loop quantities, backup options, and crew notes. Your support team knows exactly what to hand over — and when to push you to keep going.

Print-ready crew sheet

One-click print to a clean, readable sheet your crew can have at the aid station all weekend.

Train your gut before race day

Log practice runs loop-by-loop with gut, energy, and mood ratings. Dial in your nutrition in training so there are no surprises at 3am.

Food quantity specifics

Not just "eat a gel" — the plan tells you exactly how many gels, how much rice, and how many Tim Tams to have each loop.

How it works

01

Build your Athlete Profile

A 6-step quiz captures your physiology, food preferences, caffeine tolerance, and race goals. Reuse it across events.

02

Set up your Race

Enter the conditions: loop distance, temperature, terrain, elevation, crew access, and start time. Fetch live weather or enter manually.

03

Generate, Edit & Export

Instant loop-by-loop plan with exact quantities. Edit anything in plain English, save, and hand the crew sheet to your support team.

What you get

Exact quantities, not vague suggestions

Instead of "eat a gel", your plan says "2× GU Energy Gel + 1 medium banana (47g carbs)". Instead of "stay hydrated", it says "500ml Powerade (30g carbs)". Every loop, every hour.
