The memory is free. The race is paid.
Everything you touch weekly costs nothing, and it is not a trial. You pay when you are actually planning a race, which is the fortnight before an A race rather than a random Tuesday in February.
What it costs
A 100 mile entry is £200 to £400. Gels and drink mix run to hundreds across a block, and you are 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 have already paid for the fitness. Absorb is the part that remembers what your body did with it, so the day you have been training for is not the day you find out.

The weekly loop, in full. Logging, every insight, your racing record, and the day-one check against races you have already run. Not a trial and not time limited.

Founding
£100a year, forever
Everything above, and everything in Absorb. It renews at £100 rather than at the list price, so it is £99 a year less every year, not just the first.
Ask for a founding placeFounding members are also the calibration cohort. The constants behind the pacing engine were fitted against a handful of runners, and a hundred people with real race histories is what fixes that. It is why the price is permanent rather than introductory.
Absorb
£199a year
Or £20.99 a month, which is £251.88 over a year. Paying annually saves £52.88, about two and a half months of it. Monthly is a fair price rather than a penalty for not having £199 to hand.

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 an hour you are spending on admin instead of on the thing you have trained eighteen weeks for, and it is 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, their distances 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 of them 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 of them will show you what they said about your last race. | A range built section by section from terrain you have actually run. Then it rewinds to races you have already finished and shows you what it would have said, hits and misses both, so you can decide whether to trust it before it matters. |
| Your fuelling plan | An evening working out how many gels, how many chews and how much sodium, times the hours you think you will be out there. Redo the maths for the version where you are ninety minutes down. Write it into a note on your phone. Guess where on the course each one actually goes. | Your own fuelling numbers applied to each stop: what to take on, how long you mean to be there, what you need handed over. Other tools tell you grams an hour. The grams were never the hard part. Where, when, and who is holding it was. |
| Your reminders | Set a repeating timer that does not 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 taking food on is realistic and where it is 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, working out from your last tracker ping 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 are due, where to park, and what to hand you. They mark you off as you leave each stop, so the next station knows what is 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.
Reasonable objections
£199 is a lot for an app.
It is priced against what the season already costs you, not against other apps. One 100 mile entry is £200 to £400. A block of gels and drink mix runs to hundreds. Two or three pairs of shoes is another £300 to £500. Against that, a year of Absorb is less than one entry fee.
The uncomfortable version: most of that money buys fitness you already have and products you are still guessing about. This is the only line on the list that gets better the longer you keep paying it, because it is the one that remembers.
I can do this in a spreadsheet.
You can log in a spreadsheet, and plenty of good runners do. What a spreadsheet cannot do is work out the terrain, the weather, the climb and the effort of every run automatically, hold three years of history from the day you connect, and compare one condition against your own base rate across all of it.
It also cannot tell you what it would have said about races you have already run.
How do I know it works?
Check it against your own races before you pay anything. Retrodiction rewinds the engine to the morning of each race you have already finished, using only what was known before that start line, and shows you what it would have said. Hits and misses both, and the races it could not call are listed rather than hidden.
It is free, and it stays free.
I only race twice a year. Why pay for twelve months?
Because the memory is built in the months you are not racing, and that part is free. Every log, every insight and your whole racing record cost nothing. You pay in the stretch when you are actually planning a race.
Will it just tell me to eat 90g an hour?
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 are 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. A hundred members with real race histories is what turns a model calibrated for its author into one calibrated for runners.
You are the dataset, and the price reflects it permanently rather than temporarily.
