8 running, cycling, and mountain biking events in Spearfish, South Dakota

"Run for Their Lives!" is a casual and family-friendly Mother's Day 5K race/run/walk generously sponsored by Monument Health and CatholicPsych Institute.

This event is a place to gather the people that we love and participate together in memory of the ones that we are missing. It is a place to celebrate motherhood in its fullness of love, joy, gratitude, and sorrow. We invite bereaved mothers to have their children included on our list of children remembered and their names will be listed on the back of our event t-shirt. (Deadline for name submissions is April 5th)

There is no greater gift to a grieving parent than to remember their child, to say their name, and to walk beside them with a reverence for what they have lost.

2026 Highlights:

You will be able to register as one team whether you are participating in-person or virtually.

Team captains will register first and set up a team name, then all additional members can designate themselves as part of that team.

Whether you are participating in-person or virtually, part of what makes this event fun is to connect as a community!

This is where we'll share event information, photos, and a slide show of the children we are running to remember.

We would LOVE for you to share your photos of your run, your group, and your team shirts.

All proceeds from the event will go to support Lach's Legacy and the fight against SIDS in South Dakota. Lach's Legacy is a 501(c)3 non-profit organization, and works to provide comfort to newly bereaved families, SIDS and safe-sleep education, and support for SIDS-related research.
