Name: WattPace: FTP & Fuel Alerts for Tri & Cycling
Author: Nonduality

Stop guessing your race watts and stop forgetting to eat. WattPace turns your FTP into a simple, glanceable pacing system — and reminds you to fuel before it's too late, with nutrition advice that adapts to how hard you're actually working.

FTP-Based Pacing, Personalized to Your Race:
Enter your FTP once, pick your race distance, and the field calculates your exact target watts automatically:
Short TT / Crit — 95% FTP
Olympic / Short Fondo — 87% FTP
Half-Ironman / Medium Fondo — 80% FTP
Full-Ironman / Century — 72% FTP

No spreadsheets, no manual math — just pick your event and go.

Instant Color-Coded Feedback:
The entire screen becomes your pacing signal, visible at a glance without squinting at numbers:
Green — right on target
Red — pushing too hard, back off
Blue — too easy, pick it up

Includes built-in anti-flicker smoothing, so brief power spikes on rough roads or steep pitches won't cause the display to bounce back and forth — the color only changes when your effort genuinely shifts.

Adjustable sensitivity to match your riding style:
Strict Pro (±10W) · Tight Racing (±15W) · Standard Rolling (±20W) · Relaxed Hilly (±30W)

Smart Fueling Alerts — Not Just a Timer:
Most fueling reminders are just a dumb countdown. This one checks your current heart rate against your lactate threshold at the moment it fires, and adjusts its advice:
Above threshold → "H2O ONLY" — high-intensity efforts slow gut absorption, so it steers you away from solid carbs when your body can't process them anyway.
Below threshold → "TAKE CARBS" — the green light to fuel normally.

Every alert comes with a full-screen visual cue, an audible tone, and a distinct vibration pattern, so you'll catch it whether you're glancing down or head-up in the aero bars.

Fully adjustable interval — every 15, 20, 30, or 45 minutes — with your very first reminder always arriving within the first 15 minutes, matching sports-science guidance on early race fueling, regardless of your chosen cadence.

Post-Ride Data, Automatically:
Both your pacing zone and your fueling alerts are recorded as custom fields directly into your activity's FIT file — review exactly how much time you spent on target, and when every fueling reminder fired, right in Garmin Connect after your ride.

Built for Every Screen You Own:
Works on round watches and rectangular Edge bike computers alike — the layout engine adapts intelligently to your exact screen shape and size, never clipping or overflowing off the visible display.
AMOLED-safe by design — automatically switches to a battery- and screen-friendly black & white display on AMOLED devices to protect against burn-in on long rides, while showing full color on traditional always-on displays.
Scales cleanly across full-screen, half-screen, and multi-field grid layouts.

Fully Configurable from Garmin Connect:
Every setting lives in the Garmin Connect app — no need to touch the watch itself:
Your FTP
Target race type
Lactate threshold heart rate
Fueling alert frequency
Pacing sensitivity window

Perfect For:
Triathletes pacing long-course bike legs without blowing up the run
Cyclists racing time trials or crits who need precise, unwavering watt discipline
Endurance athletes who tend to forget to eat until it's too late
Anyone who wants one field to replace a raw power number and a separate fueling timer app
