Terms & Conditions

Sub24 is race-planning software for ultra runners: pacing, fuelling, hydration and crew logistics. It’s a planning tool, not a coach, not medical or nutritional advice, and not a guarantee of any race outcome. Use it as one input alongside your own training, your coach if you have one, and your own judgement.

The pacing, fuelling, hydration, sodium and caffeine guidance is general information only. It is not medical, nutritional or professional advice and is no substitute for a physician or registered dietitian. Consult a professional before acting on it, especially if you have a health condition, take medication, or are unsure about your fluid or electrolyte needs.

Ultra-distance training and racing is strenuous and carries real risks including injury, illness and, rarely, death. You take part voluntarily and at your own risk, and should get medical clearance before starting or intensifying training.

Drinking too much can cause hyponatremia (dangerously low blood sodium); too little can cause dehydration; over- or under-fuelling can cause GI distress or bonking. These can be serious. Sub24 cannot sense what is happening in your body — use thirst, sweat and how you feel as your guide, and stop or seek help if something feels wrong.

Pace splits and fuel and fluid numbers are modelled estimates from your inputs and course data — not guarantees of any finish time, performance or result. Real conditions on the day will differ. Treat every number as a starting point for your own judgement.

Distance, elevation, gradient and anything imported from GPX files or Strava are approximate and may contain errors or gaps. Verify critical details — cut-offs, aid-station locations and the course profile — against the official race information.

You must be at least 16 years old to use Sub24. You’re responsible for keeping your sign-in secure (we delegate authentication to Google), and for activity under your account.

You agree not to:

• Reverse-engineer, scrape, or automate the app at scale.
• Upload GPX files or content you don’t have the right to share.
• Harass other users or Sub24 staff.
• Access data belonging to another user, including via crew share-codes you weren’t given.

You own the content you create — race plans, nutrition, crew notes. You grant Sub24 the licence needed to host, process and display it so the app can work and improve. See the Privacy Policy for how we handle personal data.

If you connect Strava, your use of Strava is governed by Strava’s own terms and API agreement. Sub24 isn’t responsible for the availability, accuracy or data handling of third-party services. You can disconnect Strava at any time from your settings.

The Sub24 app, software and branding are owned by us or our licensors and protected by law. You get a limited, revocable, non-transferable licence to use the app; you don’t acquire any rights in it.

Sub24 is in a free alpha. It may be unstable, change, lose data, or be discontinued without notice, and we make no formal uptime or data-durability guarantee at this stage. It’s free during the alpha; if we introduce paid tiers, current alpha users will get at least 60 days’ notice and we won’t retroactively charge for past use.

Sub24 is provided “as is” and “as available”, without warranties of any kind. To the fullest extent permitted by law, we’re not liable for race performance, injury, data loss, or any indirect or consequential loss arising from using the app. Nothing in these terms excludes liability that can’t be excluded by law (for example, for death or personal injury caused by negligence).

We’ll update these terms as the app evolves and bump the version. When the terms change materially we’ll ask you to re-accept before continuing.

These terms are governed by the laws of the operator’s jurisdiction. (Placeholder — set to the actual governing law/jurisdiction before launch.)
