Run for a cause Every stride
Every stride
Fuels change
Friends pledge on your finish time — the faster you run, the more goes to the cause.

Cross the line, log your time, and pledges become donations that flow straight to your cause.

Pledges that rise with the pace
This is the heart of Grialto: every pledge carries two anchors — a finish time and an amount. Drag the handles and watch the line climb to the right: a better run means a bigger gift.
