But imagine doing it on one wheel?
Pastor Dana Simmons, his 16-year-old son Seth and 15-year-old friend Martin Morales all rode unicycles to raise money over the weekend.
Their one-wheeled ride brought in $1,500 in pledges for the Bay City, Michigan, Calvary Worship Center.
It took five and a-half hours to cover the more than 20 miles.
Of course, you can't pedal very fast on the tricky machines.
So, friends drove a pickup behind the riders with a sign warning drivers there were unicycles ahead.
