Thread the gap: precision Bump'n'Runs to a tight pin

Set up 10 piles of balls in 2 lines, each line 3 yards/meters apart. Piles are 4 yards/meters apart in each line.

Put the piles at distances between 1 and 10 yards/meters from the green, and 5 to 30 yards/meters from the hole.

On the green, make 3 landing zones with sticks or clubs, each zone 6 feet (2 meters) apart in a line.

Do 36 bump-and-run shots, aiming for each landing zone 12 times.

Hit 12 shots at the first zone, then 12 at the second, then 12 at the third. Switch piles as needed.

Count each shot that lands and stays in the correct zone as a success.

Add up successes and enter score in the app out of 36 attempts.

Arrange 40 balls into 10 piles of 4 balls each. Place the piles in two parallel lines, 5 to 10 yards apart, with each pile in a line about 2 yards apart.

On the green, mark two target zones: an inner circle with a 6-foot radius and an outer circle with a 15-foot radius.

Hit 36 shots: 18 to the inner circle, 18 to the outer circle.

Hit shots from any pile, switch between piles and lines.

Count a shot as a success if it stops in the target zone.

After 36 shots, add up successful shots and enter score in the app, out of 36 attempts.

Place two lines of 18 balls each next to the green, 1 foot apart. Lines are at right angles, 5 to 10 yards apart.

Mark 9 stop zones on the green using buckets, tees, or string. Make 3 groups with 3 zones each, spaced evenly.

Hit 36 bump-and-run shots: 12 at each group of 3 zones (4 shots per zone).

From the first line, hit 12 shots at the first group of 3 zones (4 shots per zone).

Move to the second line, hit 12 shots at the second group of 3 zones (4 shots per zone).

Go back to the first line and hit 12 shots at the third group of 3 zones (4 shots per zone). Enter score in the app, out of 36 attempts.

Count each success where the ball stops in the target zone. Add all successes for your score.
