The memory is free. The race is paid.
Everything you touch weekly costs nothing, and it isn't a trial. You pay when you're actually planning a race, which is the fortnight before an A race, not a random Tuesday in February.
They aren't two separate products either. Your finish range is built section by section from terrain you've actually run, and it tightens as you log more, so the free half is what makes the paid half worth buying. Fuelling suggestions are still general guidance, and every one of them says so.
What it costs
A 100-mile entry is £200 to £400. Gels and drink mix run to hundreds across a block, and you're still guessing which of them your gut agrees with. Shoes are £130 to £180 a pair, two or three pairs a block. A coach is £100 to £250 a month.
You've already paid for the fitness. Absorb is the part that remembers what your body did with it, so the day you've been training for isn't the day you find out.
Free
£0and not a trial
Everything about the runs you've already done. The part you use between races.
Join the waitlistWhat free gets you
- Every run logged in two taps, with 86 conditions read off it automatically: terrain, heat, humidity, time of day, how long you'd already been out
- Where your gut has actually failed, set against your own rate in every run that didn't have that condition. That comparison is the whole thing
- What the engine would have said about races you've already finished, misses shown next to hits
- Your racing record, your best efforts, and finish times corrected for the course
- Single-runner tests, the research library, and the cycle space behind its own consent
One race
£49once, and it never expires
Everything free, plus the next race planned end to end. For the runner who won't buy a year to plan one A race.
Join the waitlistWhat a race adds
- Paste the race URL. Absorb reads the page, the sub-pages, the PDFs and the scanned course images for stops, cutoffs and drop bags
- A finish range built section by section from terrain you've actually run, and where you stand against the cutoff
- Fuelling planned per stop rather than per hour: what to take on, how long you'll be there, what someone needs to hand you
- Your fuel marks written into the GPX, so they reach your watch exactly where you put them
- Kit lists for you and for whoever is handing things over
- The crew console: your plan on their phones, no account, and it works with no signal
First 100 pay £79 a year, held while you stay

Everything in a race, for every race you enter, and each one starts from what the last taught the engine about you.
Join the waitlistEverything in a race, plus

One race is £49. Three races as packs is £147; a year is £119. From the third race the year costs less, and it doesn't stop when the race does.

The logistics are their own second training block
This is the fortnight before an A race, with Absorb and without it. Every hour in the left-hand column is admin instead of the thing you've trained eighteen weeks for, and it's cognitive load you carry to the start line.
| The job | By hand | With Absorb |
|---|---|---|
| Your aid-station list | Open the race PDF, the course map and two forum threads. Cross-reference eleven stops and their cutoffs, because no two sources agree. Type them into a spreadsheet. Type them again into whatever else you use. Check them again because one moved. | Paste the race URL. Absorb reads the page, the sub-pages, the PDFs and the scanned course images, and hands you the list to confirm one stop at a time. Typed once, and it stays with the plan. |
| Your finish estimate | Take your road marathon time, apply a multiplier you found in a forum, add an hour for the vert and hope. Every tool that will give you a number leads with optimism, and none will show you what they said about your last race. | A range built section by section from terrain you've actually run. |
| Your fuelling plan | An evening of gels-times-hours arithmetic. Redo the maths for the version where you're ninety minutes down. Write it into a note on your phone. Guess where on the course each one actually goes. | Your own numbers applied to each stop: what to take on, how long you'll be there, what needs handing over. Other tools tell you grams an hour. The grams were never the hard part. Where, when, and who's holding it was. |
| Your reminders | Set a repeating timer that doesn't know a climb from a descent, then ignore it by hour eight because it went off halfway up something. Jump between three apps to get it onto your watch at all. | Fuelling zones on the course profile, so you can see where eating is realistic and where it's better to wait. Drop your marks, re-download your GPX, and they arrive on your watch exactly where you put them. |
| Your crew | A WhatsApp group, a document, a spreadsheet and a voice note, none of them the current version. Someone parked at the wrong checkpoint with no signal, reading your last tracker ping to work out whether they have ten minutes or two hours. | You plan the race once and it becomes their plan too. Their own page on their own phone: every stop in order, when you're due, where to park, what to hand you. They tick you through each stop, so the next one knows what's coming. It works with no signal. |
Crewing is as hard a day as running it, done unpaid, usually by someone who loves you. Every other tool treats them as a PDF to send. They get their own space here.
Before you decide
How does the price compare to what I already spend?
It's priced against what you already spend on the same problem, not against other apps. A sweat test is around £125, paid once, for one number. A block of gels and drink mix runs to hundreds a season. One 100-mile entry is £200 to £400. Coaching is £100 to £250 a month.
A year of Absorb is less than a single sweat test, and it keeps working. Most of that list buys fitness you already have and products you're still guessing about. This is the one line on it that gets better the longer you keep it, because it's the one that remembers.
My watch already does my fuelling.
It reminds you. That's a different job. Every watch worth owning will buzz on a timer you set yourself. None of them asks what happened next, so none of them knows whether it worked.
Your watch gives the same prompt on the flat, on a twenty per cent climb at hour fourteen, and again next year, having learned nothing from either. It has no record of the run where your stomach turned, and no way to tell you the last four times in this heat went the same way. Absorb is the part after the alarm goes off.
I can do this in a spreadsheet.
You can log one in a spreadsheet. What a spreadsheet can't do is work out the terrain, weather, climb and effort of every run automatically, fill in 24 weeks the day you connect and keep reaching back across a full year, and compare one condition against your own base rate across all of it.
It also can't tell you what it would have said about races you've already run.
How do I know it works?
Use it for nothing, for as long as you like. Logging, every pattern and your full racing record are free forever and not a trial, so you can run months of your own training through it and decide whether it tells you anything true before a race pack is ever in question.
It's free, and it stays free. See the races it got wrong.
I only race twice a year. Why pay for twelve months?
Don't. One race is £49, paid once, never expires, so you buy it in the fortnight you're actually planning and you're done.
Three races as packs is £147 against £119 for the year, so the year only starts making sense from the third race. The part you use between races, every log, every pattern, your whole racing record, is free either way.
Will it just tell me to eat 90g an hour?
No. Absorb never prescribes and never claims a cause. It shows what your issues have coincided with, with the number of runs behind it, and says nothing when the sample is too thin. That rule is enforced by code that refuses to start if the copy breaks it.
Why is it cheaper for the first 100?
Because you're doing something for us. Every tuning constant in the pacing engine is currently fitted against a handful of runners, and the internal audit explicitly warns against tuning further on that sample. Founding members are the people telling us where it is wrong, on races we have never seen. Your own race history calibrates your own model, and nothing of yours is pooled with anybody else's.
You are the dataset, and the price reflects it permanently rather than temporarily.
