My kids race mountain bikes and send me their strava beacon. I'm hoping to be able to pull their real time location data (and maybe their teammates) and put it on a map where the family members who are at the race can see where everyone is on the course. Picture beacon as it is now but with multiple riders on the screen at once. 

I might be missing this somewhere but I cant tell if the Get Activity Streams would be able to give me the strava location data in real time. 

I tried using the Swagger Playground (and the API via postman) but I cant figure out how to get the activity ID of an activity that is currently being recorded. Any suggestions? 

Thanks!
