Program Overview

Endurance HQ Event Notifications

Endurance HQ sends SMS/text messages related to endurance sports events you register for or volunteer at. Messages are transactional and informational only — no marketing or promotional messages are sent without separate explicit consent.

Types of messages we send:

  • Race day reminders and packet pickup information
  • Schedule changes and start time updates
  • Course reroutes and weather alerts
  • Volunteer shift reminders (24 hours before and morning of)
  • Emergency and safety notifications
  • Event cancellation or postponement notices

How You Opt In (Call to Action)

Endurance HQ never sends unsolicited text messages. You must provide explicit consent before receiving any SMS notifications. There are two ways to opt in:

Participant Registration

When registering for an event on Endurance HQ, you will see an optional SMS consent checkbox on the waivers and agreements step of the registration form. The checkbox reads:

I agree to receive event-related SMS notifications

Receive race day updates, schedule changes, and emergency alerts via text message. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out, HELP for help. Privacy Policy & Terms.

This checkbox is not checked by default — you must actively check it to opt in. SMS consent is not required as a condition of event registration. You can register for any event without opting in to SMS notifications.

Volunteer Signup

When signing up to volunteer for an event, you will see an optional SMS opt-in checkbox on the signup form. The checkbox reads:

Send me SMS shift reminders

Receive text reminders 24 hours before and the morning of your shift, plus emergency alerts. Msg frequency varies. Msg & data rates may apply. Reply STOP to opt out, HELP for help.

This checkbox is not checked by default — you must actively check it to opt in. SMS consent is not required as a condition of volunteering. You can volunteer without opting in to SMS notifications.

Volunteers can also manage their SMS preferences at any time through the volunteer settings dashboard, which includes an SMS toggle switch.

  • Message frequency varies by event. You will typically receive 1-10 messages per event you are registered for or volunteering at. Additional messages may be sent in urgent or emergency situations.
