Privacy Policy

Last updated: October 26, 2026

Overview

Multiday Running (“we,” “us,” or “our”) respects your privacy. This policy explains what information is processed when you use this website. The site has no user accounts or payment form. It includes analytics and Journey by Mediavine advertising, described below. The only form that sends personal information is the optional newsletter signup described below.

Information Processed When You Visit

Hosting and Security Data

The site is hosted by Vercel. Like other web hosts, Vercel may process technical request data needed to deliver and protect the service, such as IP address, request time, requested URL, browser information, and security logs. Vercel handles that information under its own data-protection terms.

Aggregate Web Analytics

We use Vercel Web Analytics to understand aggregate traffic, such as page views, referrers, device type, browser, and approximate region. We do not send names, email addresses, or custom user identifiers to analytics. Vercel describes these analytics data points as anonymous and not associated with an individual or IP address. See Vercel's Web Analytics privacy documentation.

Google Analytics

We also use Google Analytics 4, provided by Google, to measure how pages are found and used, such as page views, scrolling, outbound link clicks, referrers, device and browser type, and approximate location. Google Analytics sets first-party cookies (_ga and _ga_*) to recognize a browser across visits and may process your IP address to derive approximate location; Google Analytics 4 does not log or store IP addresses. We do not send names, email addresses, or custom user identifiers to Google Analytics.

If you visit from the EU, the wider European Economic Area, the United Kingdom, or Switzerland, Google Analytics loads only after you consent to it in the consent banner, where it is listed as “Google Analytics.” Elsewhere it loads by default. In those regions you can change your choice at any time with the privacy settings link at the bottom of every page; withdrawing consent stops further measurement and deletes the Google Analytics cookies. You can also block it with your browser's tracking protection or Google's opt-out browser add-on.

Journey by Mediavine Advertising

We use Journey by Mediavine to deliver advertising. Mediavine and its advertising partners may process IP addresses, device and browser information, approximate location and browsing activity. Cookies, pixels and similar technologies can support ad delivery, measurement and interest-based advertising, including sharing data with advertising partners. See Mediavine's privacy notices and advertising choices.

Advertising preferences are managed through Mediavine's regional privacy controls where available. In the EU, the wider European Economic Area, the United Kingdom, and Switzerland, the same consent banner covers advertising and Google Analytics, and you can accept or reject each provider separately. Mediavine explains its opt-out tools and privacy requests in the linked privacy center.

Email Contact

If you select an email link, your email application opens and you choose whether to send a message. That message is processed by your email provider and ours; it is not submitted through this website.

Newsletter

The weekly newsletter is optional. If you sign up, our server sends the email address you enter to beehiiv, the newsletter service we use, together with the page you signed up on. On race and result pages it also sends the race shown there, which beehiiv saves as a tag on your subscription so we can send you that race's result or next-edition news. You then receive an email asking you to confirm. Nothing else is sent until you click the confirmation link.

beehiiv records whether newsletter emails are delivered, opened, and clicked, which shows us which stories subscribers find useful. beehiiv may process subscriber information in the United States under its own privacy policy. We use your email address only to send the newsletter you asked for, and we do not sell or rent it. We process it based on your consent, which you can withdraw at any time with the unsubscribe link in every email or by asking us at the contact address below.

How Information Is Used

  • To deliver, secure, and troubleshoot the website
  • To understand which pages are useful in aggregate
  • To deliver and measure advertising through Journey by Mediavine
  • To send the newsletter to subscribers who confirmed their signup
  • To answer messages you choose to send by email

Third-Party Services

We use the following third-party services that may process data:

Cookies and Local Storage

Advertising may use the cookies and similar technologies described above. When analytics is allowed, Google Analytics sets the cookies described above. A session cookie (multiday-consent-required) records only whether your country requires analytics consent, based on the country our host derives from your IP address; it contains no identifier. Mediavine's consent banner stores your consent choices in cookies on this site. Saved race shortlists and crew plans that you choose to save are stored in this browser’s local storage. They remain on this device until you remove them or clear site data. Other calculator and checklist entries are not saved between visits. Shared comparison links contain the selected race identifiers; anyone with the link can see that comparison. They do not include your crew-plan notes. Infrastructure providers may use strictly necessary technologies to operate and secure their services.

Retention

Aggregate analytics are retained according to the site's Vercel plan and settings. Google Analytics data is retained for the period set in our Google Analytics data-retention settings. Newsletter subscriptions are kept until you unsubscribe or ask us to delete them; beehiiv may keep a record of an unsubscribe so the address is not emailed again. If you email us, we retain the message only as long as reasonably needed to respond, keep necessary records, or meet legal obligations. You may ask us to delete a message unless retention is legally required.

Your Rights

Depending on where you live, you may have rights to request access, correction, deletion, restriction, or objection regarding personal information we control. You may also complain to your local data-protection authority. To make a request, use the contact address below. We may need enough information to verify and handle the request.

Children's Privacy

Our site is not directed at children under 16. We do not knowingly ask children to provide personal information through the site.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date.
