The bell outranks the clock.
Betweenloops is a race-day nutrition tracker for Backyard Ultra crews. Log what the runner takes in, round by round, so intake stays ahead of the next bell instead of being reconstructed afterwards.
Double opt-in. One email when it is ready, and nothing else.
The crew is awake as long as the runner.
A Backyard Ultra starts a fixed loop on a fixed interval. The runner comes back and rests whatever is left of the hour — a few minutes, and then the bell again. That gap is where nutrition is decided, and it is the same gap in which everything else has to happen.
Past the twenty-hour mark the handler at the aid station is sleep-deprived, cold, and working in the dark, with wet or gloved hands. Intake noted on a damp sheet of paper is intake reconstructed afterwards, if it is recovered at all.
Built around the minutes between loops.
One tap, and undo
Quick-add books an item at quantity one. A toast offers the undo, and removing the youngest entry is a single gesture. Every write is reversible, because a mis-tap at 3 a.m. has to cost nothing.
Five channels, per-round targets
Carbs, sodium, fluid, protein, and caffeine, each with a target for the round. The current gap is what the screen shows first; the numeral changes state once the target is met.
Rounds are derived, never scheduled
The round number is computed from the event start and the round length, so there is no pre-generated schedule to drift out of sync. When the race leaves the grid, the bell sets the round start to now.
The drift across hours
A second surface plots every round against its targets. A fluid or sodium line that is quietly slipping shows up there long before the runner feels it, and dragging across the chart moves the whole view to that round.
Designed for 3 a.m., and for the sun after it.
- Darkness
- The screen is the light source in a dark station, and eyes are dark-adapted. The theme is dark and does not switch.
- Fatigue
- Past twenty hours, cognitive load and error-proofing outrank information density.
- Gloved hands
- Rain, sweat, and cold fingers. Tap targets run to 144 px, and mis-taps are recoverable.
- Direct sun
- The same glossy iPad has to stay legible in daylight. Contrast is a functional requirement, not a preference.
Built narrow, on purpose.
Betweenloops covers one race, one crew, one screen — the hours between the first bell and the last, for the person holding the iPad at the aid station.
It is deliberately not a training platform and not a planner. It is early, and it is built for one crew before it is built for anyone else.
