COACH — Bikepacker at checkpoint, dusk
A bikepacker at a remote checkpoint in the badlands at last light — bike leaned against a weathered fence post in the right half of the frame, frame bags covered in fine red dust, rider out of focus sitting on the ground refilling bottles. Wide cinematic composition, deep golden-magenta sky over red-rock mesas, a single low service-station shed at the right edge. Left third of the frame in deeper shadow to support text overlay; right third opens up to a dark warm sky behind the phone-mock area. Documentary editorial, shot on 35mm with subtle grain, no race-brand kit, no logos.
03 — The App
A coach
in your
pocket.
Marginal Gains Coach is our iOS app. It plans your training, watches your recovery, and adjusts the week before you have to ask. Quietly, in the background — built for the triathletes, ultra-runners, and bikepackers whose calendars don't look like everyone else's.

Screens
TODAY — Readiness + plan
Stylized iOS app screen mockup, dark charcoal background, top: small Marginal Gains logo mark in clay color and date 'TUE 14 MAY' in cream. Center: large italic semibold display number '87' in cream as the readiness score, a small clay-color label 'GO HARD TODAY' beneath it. Lower: a clay-accented workout card 'VO₂ INTERVALS · 1H05 · 5×4min @ FTP+12'. Bottom: minimal tab bar with three icons. Editorial UI mockup, palette charcoal/clay/cream, no iOS chrome details.
WORKOUT — Intervals timeline
Stylized iOS app screen mockup, dark charcoal background, top: workout title 'VO₂ INTERVALS' in italic semibold cream. A horizontal interval timeline showing 5 alternating clay/charcoal blocks for work/rest, scaled to time. A small power-zone bar chart in cream/clay/warm-gray below. A list of three target metrics (POWER · CADENCE · RPE). A primary clay button labelled 'START' at the bottom. Editorial UI mockup, charcoal/clay/cream palette.
TREND — Fitness/fatigue chart
Stylized iOS app screen mockup, dark charcoal background, top: section label 'FITNESS / FATIGUE' in clay. A wide area chart showing two overlapping smooth curves over 12 weeks — one rust-clay (fitness), one warm-gray (fatigue) — with a vertical 'TODAY' marker. Below: a weekly summary row showing three cream pill-shaped stat cards (TSS · DURATION · ELEV). Editorial UI mockup, charcoal/clay/cream palette.
Features
What it actually does.
Adaptive Training
Your plan rewrites itself when life happens. Miss a session, do an extra one, sleep four hours — the next week adapts to what your body actually did.
Lab-Grade Metrics
Threshold, VO₂ proxy, durability score. The same numbers we calculate in the studio, computed continuously from your rides and runs.
Recovery & Readiness
HRV, sleep, training load. A daily readiness score actually built on a model — not three arbitrary inputs and a wellness emoji.
Built for the Long Stuff
Multi-day bikepacking, Ironman blocks, ultra-trail tapers. Most apps forget what training for a 24-hour event looks like.
