Update Date Display Logic on Group Pages

On Group Pages (e.g., https://ultrasignup.com/groups.aspx?gid=452), the event date currently displays the end date, which can be misleading—especially for multi-day events where longer distances (like 100 milers) start earlier in the weekend.

Feature request:

Update the display to show the start date of the earliest distance instead of the event’s end date

Or offer an option to customize which date is shown on the group page

This would provide clearer, more accurate information for runners browsing multiple events.
