The Strava community is filled with athletes combining running and biking into single, dynamic sessions—whether for duathlon training, brick workouts, or adventure days mixing trails and roads. Adding "Run and Bike" as a sport would better reflect these hybrid activities. Ideally, sporters could determine when they were on the bike, when by foot and when uncertain.
This combination mechanism could also extend to other sports, like triathlon? As you would not need anymore to start a new activity between cycling and running.
