Terms of Use

Swim Pace Calculator is a free informational website operated by Ian Welkins. It provides calculators, charts and explanations that turn swim times, distances and paces into training figures, using formulas and data from the published sources named on the Methodology page. By using this site you accept these terms. There are no accounts and nothing to buy: the tools are provided as-is, for general information and training planning, and using them costs nothing and creates no relationship — coaching, professional or otherwise — between you and the site.

Every number this site produces is an estimate. A pace, split plan, conversion or predicted finish time calculated here is not official race timing, does not replace the timing, results or rulings of any meet, federation or event organiser, and must not be presented as an official result. Course conversions use published average factors; governing bodies and meet organisers apply their own rules, and their determination is the one that counts. Nothing on this site is coaching advice for your individual circumstances, and nothing on it is medical advice. Training decisions — including how hard to train, and whether to train through pain, illness or injury — are yours, and where health is concerned they belong with a qualified medical professional. If you work with a coach, their judgement about your swimming outranks any figure produced here.

The formulas, factors and values used here are taken from the published sources named on each page, and the site's checking process is described in the editorial policy. Even so, no warranty is given that any figure is accurate, complete or current. Sources are revised, conversion systems differ, and real swims vary with turns, course measurement, conditions and the swimmer. Worked examples are verified against the site's own code, but errors can still occur — and when one is found, the correction process in the editorial policy applies. You are responsible for checking any figure you rely on for something that matters, such as a race entry time, against the relevant official source or organiser. If you find an error, please report it through the report-an-error page.

You may use this site for your own training, coaching, club and educational purposes. You may not use it in a way that breaks the law, attempt to disrupt or overload the site or its hosting, misrepresent the site's estimates as official results, or present the site's content as your own work. Automated access that imposes an unreasonable load on the site is not permitted; ordinary linking, quoting and printing under the section below are welcome.

The text, tables, design and code of this site belong to its operator or are used under licence, except for the published source material credited to its owners. You may quote reasonable extracts of the site's content — a pace table, a formula, a passage — in your own articles, club materials and teaching, provided you credit Swim Pace Calculator and link back to the page you quoted. The swim pace chart may be printed and reproduced for personal and club use — on a pool wall, in a squad handbook, in a race pack — without asking, provided it is not sold and the site's name stays on it. Anything beyond this, including republishing whole pages or building a competing tool from the site's content wholesale, needs written permission first; ask by email.

To the extent permitted by law, the operator of this site is not liable for any loss or damage arising from your use of the site or your reliance on any figure it produces — including a missed cut-off, a race plan built on an estimate, or a training decision informed by a calculation. The tools are planning aids offered free of charge; the decision to act on them, and the consequences of that decision, remain yours. Nothing in these terms limits liability that cannot lawfully be limited.

These terms are governed by the laws of the United States. Any dispute arising from them or from use of this site is subject to the jurisdiction of the United States courts. If any part of these terms is found unenforceable, the remaining parts continue in full effect.

These terms may be updated as the site changes; the date at the top of this page moves when they do, and continued use of the site after an update means you accept the updated terms. Questions about these terms go to Ian Welkins at ianwelkins@gmail.com, or through the contact page.
