Horse race or bicycle race?
In ancient Central Asia, people loved to ride horses and often raced their horses for fun. You probably don’t have horses you can race (though that would be a great activity if you do!) but you might be able to race bicycles instead.
Can you organize a bicycle race activity? Can you hit a target with a ball while riding your bike?
Bike races or bike polo?
You don’t need to be very organized, with numbers and timers – you can just get a group of kids together with their bikes and race down your block, or across a big parking lot near your houses.
Or, if this bike race is part of a “day in Central Asia” event, you could race your bikes across a field.
