Group Activity.
Trailhead to finish line.
Five people meeting at a trailhead, two of whom are new friends-of-friends. They want to share beacons for the workout but not exchange numbers or set up trusted contacts. PeakPulse makes it a thirty-second QR scan: scan, join, run, disband.
The trailhead problem
Trusted contacts are the right tool for the people in your life — partner, training partner, parent. They persist across workouts. But the trailhead is full of impermanent groups: the local trail club Saturday run, a stranger's friend who came along, a one-off race-prep ride. You want to be visible to those people today, not forever.
Setting up trusted-contact relationships for a one-time group is the wrong shape. Group Activity is the right shape: ephemeral, scoped to the workout, automatic teardown.
Some friendships last a year. Some last a Saturday run. PeakPulse lets you share appropriately for either.
How it works
-
01
One person creates the group
From the pre-workout screen, tap "Start a group." PeakPulse generates a QR code and a deep link. The host is the first member.
-
02
Others join with a scan or tap
The QR code is for in-person ("scan this"). The deep link is for group chats ("everyone tap this"). Either path lands the joiner on a confirmation sheet where they accept the group's terms — share my beacon with these people, for this workout.
-
03
Everyone starts their workout
When members tap Start, their beacons automatically include the rest of the group. The Co-Running Overlay shows every member's dot on every member's map.
-
04
The group disbands when the workout ends
When members finish, their beacons stop. When the last member finishes (or after a timeout), the group itself dissolves. No leftover relationships, no settings to clean up.
What a group includes
Common questions
Do I have to be in cell range to create or join a group?
At setup time, yes — the QR code and deep link rely on the server to coordinate membership. Once the group is live and everyone has joined, the workouts proceed normally even if the trailhead loses signal: beacon updates queue and flush like always.
What if someone doesn't have PeakPulse?
They can't join the group as a member, but you can still share your individual beacon link with them as a viewer — they'll see your live workout in a browser, same as Live Beacon. The group is for fellow-recorders.
Will I see members in my history?
The workout you recorded keeps a non-identifying record of the group ("Saturday Trail Run, 5 members"). You can see who was in the group only if they've also saved their version to share with you. Privacy is preserved unless people opt in.
Can a group span multiple workouts?
No, by design. A group is for one workout. If you all run again next Saturday, you create a new group. This keeps groups disposable and the underlying trust model simple.
What if I want to keep in touch with someone I met in a group?
From the group sheet you can add a member as a trusted contact, which is a separate, persistent relationship. The group still disbands on its own.
