What You Get

12 weeks of training that actually works.

The build most runners get wrong, base, threshold, long runs, taper. Sequenced properly and written out day by day, so you just show up.

01

Daily sessions, ready when you wake up.
Today's run, the warmup, the cool down, sorted. No flipping through pages.

02

Coach notes on every session.
Why you're doing this run, what it should feel like, what to do if it doesn't.

03

Every run logged automatically.
Distance, time, heart rate, zones. See if your easy runs are actually easy.

04

Check-ins when you skip.
Miss a session? You'll hear from me. No guilt, just a coaching reset.

Today, sorted

Today's session, ready every morning.

Open it up and the day's run is right there. Warmup, intervals, cool down. With coach notes telling you why this session matters and what you should feel.

Today's session
Coach in your corner

Skip a session? I'll check in.

Miss a scheduled run and you'll get a check-in, no shame, just a coaching reset. Take the rest day, mark the missed session, or pick up tomorrow. The plan absorbs it. This is what stops good plans turning into 4 days of effort and a quiet retreat.

Missed run check-in
Every run logged

Log every run in 10 seconds.

Distance, time, heart rate. Sparkies calculates your zones and tells you whether your easy run was actually easy, or whether you accidentally turned it into a tempo. Most runners are running their easy runs too hard. This is the safety net.

Real Runner

This is what real feedback looks like.

Recent run from Treasa, one of the Sparkies runners. 5.72km at her target heart rate. Coach comment generated from her actual zone data.

Real feedback on every run. Automatic. In seconds. This is the difference between training and just running.

Who This Is For

If any of these sound like you.

01

You can run 10km and want to get to 21.1 without falling apart in the back half.

02

You've run a half before and want to actually race it this time, not just survive it.

03

You keep stacking mileage with no real structure and wondering why you have plateaued.

04

You want the long runs, the threshold work, and the taper planned for you, so you just run.

Quick Answers

Before you sign up.

How does pricing work?
Running and logging are free forever, no card needed. The half plan is part of Coach, $4.95/mo at the founding member price (normally $14.95), which also unlocks every other race plan, the recovery protocol, Strava sync and the AI coach. Cancel any time from your profile or the Stripe portal and you drop back to the free tier.
What is in the 12-week plan?
Aerobic base, threshold and tempo work, race-pace long runs that build toward the distance, and a real taper into race week. Every session is written out, warmup to cool down, with coach notes on why it matters and what it should feel like.
Do I need to have run before?
Yes. The half assumes you can already cover around 10km. If you are not there yet, start on The Base, it is free, build the aerobic engine first, then come back for the half.
Can I cancel anytime?
Yes. Cancel from your profile or the Stripe customer portal, no retention dark patterns. Cancel during the trial and you are never charged. One subscription also unlocks every other plan, not just the half.
Can I use it on my phone?
Yes. Add it to your home screen and it works like any other app. iOS and Android both supported.
