I think runners playing basketball is infinitely more fun than watching people who actually know how to play. Which specific NCAA athletes would you pay more money to watch in a pickup game than to see the same old Zion Williamson dusting a bunch of scrubs? Bailey Roth versus Rory Linkletter? Vincent Kiprop versus Alex Ostberg? I think there's a lot of potential to discuss where the best dynasty of distance-runners may be.
Biathlon for running. Lap on the track, shoot a 3 point shot, miss run an extra lap penalty (could be full 200 or shorter loop).
