Terms of service

PaceIQ estimates a Comrades Marathon finish time from the training you have logged. It is an independent project. It is not associated with, endorsed by, or affiliated with the Comrades Marathon Association, and all Comrades Marathon trademarks belong to their owners.

The service is provided free of charge. There is nothing to pay and nothing to cancel.

You must be 18 or older. See the privacy policy for why that line is drawn where it is.

You must have the right to the Strava account you connect. Do not connect an account that is not yours.

One account per person. Do not share your login.

This is the part worth reading twice. A predicted time is a statistical estimate from your training history and past Comrades results. It is not a promise, a target set by a coach, or a medical opinion.

A great deal that decides a race day is invisible to us: illness, injury, heat, how you slept, what you ate, whether you went out too fast. The model does not see any of it.

We publish our own accuracy, including the races we got badly wrong, so you can judge for yourself how much weight to give the number. Please do.

Decisions you make on the basis of a prediction - how you pace, how you train, whether you enter - are yours.

Nothing here is medical advice. Ultra-distance running carries real risk. Speak to a doctor before starting or substantially increasing training, particularly if you have a heart condition or any history of cardiac symptoms.

If the service suggests you could train more, that is an observation about data, not a recommendation about your body.

Connecting Strava authorises us to read your activities so we can build a prediction. You can disconnect at any time from Strava's own settings or by deleting your account here.

We use that data to serve you, and in aggregate to improve the model and publish statistics about the field. Aggregate figures never identify an individual.

Strava's own terms govern your relationship with Strava. Where they conflict with ours regarding Strava data, theirs apply.

Do not attempt to scrape the service, overload it, reverse-engineer it, or access accounts that are not yours.

Do not present output from PaceIQ as official Comrades Marathon information. It is not.

We may suspend an account that does any of the above.

This is a small independent project, largely run on one server. We make no promise about uptime and may change or withdraw features without notice. If we ever shut the service down we will give notice and a way to export your data first.

To the fullest extent the law permits, PaceIQ and its creators accept no liability for any loss, injury or damage arising from use of the service or reliance on anything it produces.

Nothing here excludes liability that cannot lawfully be excluded, including for death or personal injury caused by negligence, or for fraud.

These terms are governed by the laws of the Republic of South Africa, and the South African courts have jurisdiction.

We may update these terms. Material changes will be shown in the application before they take effect, and the date at the top of this page will change.
