SUB. Marathon Pace & Training
Sports
Uniquement pour iPhone
Gratuit · Conçue pour iPhone. Non validée pour macOS.
[Stop training blind. Let the data define your peak.]
SUB is the marathon training partner built for Garmin and COROS runners. Connect your watch once and every run syncs automatically. Pick a goal — Sub-3, Sub-3:30, Sub-4 — and SUB turns it into per-kilometre target pace, the right races, and coach workouts that tick themselves off the moment your watch syncs. Free. No subscription. No ads.
Whether you're chasing your first 5K or a sub-3 marathon, SUB plans your next race with science, not guesswork.
CORE FEATURES
1. Connect once, then it's automatic
• Garmin — every Forerunner, Fenix, Epix and Venu; runs land within minutes
• COROS — Pace 3, Apex 2 / 2 Pro, Vertix 2, with full running dynamics and lap detail
• Apple Watch (via Apple Health) and Polar
• Use Garmin and COROS together — mileage is de-duplicated, never double-counted
2. Goal-driven pacing
• Pick Sub-3 / Sub-3:30 / Sub-4 and get target pace per km or mile, plus 5K, 10K, half and 30K splits
• Pace calculator for any distance and finish time, with a track mode for lap splits
3. Running Fitness engine
• Elite-grade model: Daniels–Gilbert. Enter a recent result and unlock your fitness level
• Five scientific training paces — E, M, T, I, R — no more guessing at effort
• Race predictions from 5K to the marathon to shape your SUB strategy
4. Coaches and clubs
• Coaches assign long runs, intervals and tempo; they auto-complete when a matching run syncs — no manual logging
• Coached classes and running clubs across Hong Kong
5. Race intelligence
• Races in Hong Kong, Japan and worldwide: dates, venues, distances, entry windows
• Save races with one tap; countdowns live on your Home Screen widget
6. Built for Hong Kong runners
• Live sports ground availability — opening slots and bookings for every public track
• Real-time running weather
• Monthly challenges with live rankings
Also: Apple Watch app, weekly / monthly mileage widgets, leaderboards, English / Traditional Chinese / Japanese.
WHY SUB?
Because running isn't magic — it's oxygen engineering. Garmin Connect and COROS Training Hub log your runs; SUB turns that data into a goal, a pace and a plan, so you can put your energy on the road.
Download SUB free. Never miss a race — or a chance to get stronger.

What's New
**Ranked Challenges: Every Kilometre Counts**
No target. No cap. This month's challenge is a straight race for the most kilometres — and your live rank sits right on the card, so you always know exactly who's ahead and by how much. Time to chase them down.
**Never Miss an Update**
A newer SUB on the App Store? You'll see a gentle banner the moment it lands. One tap to dismiss, and it stays out of your way until the next release.
**Running Fitness, Right Where You Left It**
The 跑力分析 tab now remembers your place and the times you typed, so you can jump back in without starting over.
**Coupons, Redeemed in One Tap**
Show your code, staff tap confirm, done. And if a code times out, the screen now tells you and lets you try again.
**Sharper Track Calendar**
The sports ground calendar stops at the last published date instead of paging into empty months.
**Rock Solid**
Brief connection hiccups no longer show up as crashes. SUB now requires iOS 15 or later.
