Who built this?

One person building it, with a coach shaping it.

That is the whole team. It is the reason the fields match the sport, and the reason a bug you report gets looked at the same week.

  • The build

    One person writes the software

    No team, no investors, no roadmap written by someone who has never run a session.

  • The check

    A sprint coach shapes it

    Every decision about what a session holds gets argued with someone who coaches for a living.

  • The result

    The fields follow the sport

    A sprint asks for distance and time, a lift for reps and load. That came from coaching, not from a spec.

Before you sign up

Let me set it up with you.

Free, and with the person who writes it. Tell me about your squad and I'll email you to find a time. We put your athletes, your groups and your first block in together, live. Right now the walkthrough is the product.

Start your setup
Isn't one person a risk?

Yes, and it is the honest trade. What you get for it is that nothing on this page was written by a marketing team, every claim traces to code that runs, and the person who reads your email is the person who fixes it. What you give up is the reassurance of a large company behind it. If that trade is wrong for you, it is genuinely wrong for you.

How do I get my week in?

Never enter the same week twice.

Plan one week. Copy it onto the weeks after it, then change only what's different.

Build it, paste it or photograph it, once.

Sprinter — iOS CompanionComing Soon

The lab in your pocket.

Sprinter turns the phone already in your pocket into trackside measurement gear — neural readiness, reaction, stride mechanics, sprint splits. Seven tools. One phone. Feeding the same training system.

Sprinter measures: CNS tap test, reaction time, block start, plyometric RSI, stride analysis, distance, and sprint timing.

Should I sign up at all?

Four reasons to not start yet.

We would rather you came back in October than started this week and found the thing you needed missing.

  • You want your gate exports read automatically.

    Nothing reads a Freelap, Brower or Dashr file on its own. Athletes type the splits themselves and the set time is their sum. Switch a sprint to Freelap and they also see the speed over every split. While we are this small, send us the file and we will bring it in by hand.

  • You want it to tell you the programme is too aggressive.

    It answers when you ask it. Nothing reviews your block and warns you off it, and nothing compiles your week for you. Both are on the list. If that is the reason you would sign up, wait for it.

  • You are mid-block and don't want anything to move.

    Start at your next block instead. Nothing here needs your season backfilled, so there is no advantage to starting in the middle of one.

  • You want it to tell you whether the block worked, this block.

    The squad comparison runs on a rolling 90 days: the last six weeks against the six before them. It needs about six weeks of logged sessions before a difference means anything, and it does not line up with your block boundaries. Top lifts and completion rates are there; sprint times only feed it when they arrived as timing-gate data, so that column stays empty if you type times in. If you would sign up for a verdict on the block you are writing now, that is not what this does yet.

Either way, one thing holds: the numbers you'll wish you had in March are the ones somebody wrote down in September. That is as true in a notebook as it is here.

Answers

Frequently asked questions

Sprinting uses AI to help you build and modify training plans through natural conversation. During a workout, you can chat with the AI assistant to add exercises, swap movements, or adjust sets and reps. The AI understands training principles and adapts suggestions to your context. The group review, the photo parse and Ask each start with you asking: none of them runs on its own.

No. Each athlete signs in with their own account and you invite them as they come. Put next Tuesday in first, then add whoever turns up to it. An athlete added after you published still gets that session. Leave the twelve-year-olds on paper until you're ready.

Yes, in metres and seconds rather than kilos and reps. A sprint asks for a distance and a time, a bench triple asks for load, and each movement shows only the fields it needs. No kilos on a flying 30. A rep can carry its structure too: an in-out written 30|10|30, a fly off a 20 m build, or 2 × 200 with a minute between. You mark the part the clock covers, so the distance is what the time measured and an in-out 30 never counts as a flat 30. Athletes can type a time for each gate or section, and the set time is their sum.

Yes, by hand. Switch a sprint to Freelap in its Fields menu and split the rep the way you time it, say a 20 m build, then 10, 10 and 10 on the clock. Your athlete types each split, the set time is their sum, and the table works out the speed for every split. Nothing reads the device or its files on its own yet.

Yes. Sprinting supports coach-athlete relationships natively. Your coach can create training programs, assign them to you, and monitor your progress. Athletes log workouts and the data flows back to the coach. Both roles work within the same platform.

Sprinting supports strength training, running, sprinting, and general athletic training. Sprint work is logged in distance and time per rep, with velocity on flying runs where you record it, alongside periodized training blocks for structured programs and a comprehensive exercise library. The platform is designed to handle any training that involves sets, reps, or timed efforts.

Yes. All data is encrypted in transit and at rest. We use Supabase for our backend infrastructure with row-level security policies. Your training data is private by default — coaches can only see data from athletes who have explicitly connected with them.

Sprinting is a web application that works on any modern browser — desktop, tablet, or mobile. It is built as a progressive web app (PWA), so you can install it on your home screen for a native app-like experience on iOS and Android.
