Feel the green—leave every Bump'n'Run inside the safe zone

Put 40 balls in 8 lines of 5 balls each around the green. Lines should be about 1 yard/meter apart and placed 1 to 10 yards/meters from the green and 5 to 30 yards/meters from the hole.

On the green, mark two circle zones around the hole: one with a 6-foot (2 meter) radius and another with a 15-foot (5 meter) radius.

Hit 36 bump-and-run shots—first 18 shots aiming for the small inner circle, then 18 shots aiming for the bigger outer circle.

Use any line of balls. Hit shots for the inner circle for 18 attempts, then switch to hitting shots for the outer circle for another 18 attempts. Change lines as wanted.

Count each ball that stops in the circle aimed for as a success.

After all 36 shots, add the number of successful shots out of 36 and enter your score in the app.

Make 10 piles of 4 balls (40 balls) in two lines, crossing each other near the green, 1 to 10 yards from the green and 5 to 30 yards from the hole. Keep piles 2 yards apart, lines 5 to 10 yards apart.

On the green, use string or tees to mark two circles around the hole: one with a 6-foot radius (inner), the other with a 15-foot radius (outer).

Use only 36 balls (9 piles of 4) for this test.

Split the 36 shots into two groups of

For the first 18 shots, try to land the ball inside the small circle.

For the next 18 shots, try to land the ball inside the big circle but outside the small circle.

Play bump-and-run shots by hitting from different piles, one after the other, keeping the same setup and order.

Count as a success if the ball stops in the correct circle. If not, it is a miss.

Count how many balls finished where they should in both circles. Enter your score in the app, out of 36 attempts.

Set up 4 rows of 9 balls each, spaced 1 foot apart. Each row is 3 yards apart.

On the green, use strings or tees to mark 4 circles, each 6 feet wide.

Hit 9 balls at each circle, for a total of 36 shots.

Start at any row. Hit 9 balls at the first circle, then the next 9 at the second, and so on for all circles.

Keep the balls in the same place and aim at the target circle each time.

Count how many balls stop inside each circle after 9 shots.

Add up the number of balls that stopped inside the target circles out of 36, and enter score in the app, out of 36 attempts.

Set up 9 piles of 4 balls each, spread between 1 and 10 yards from the green and 5 to 30 yards from the hole.

Mark 9 stop zones on the green using tees, string, or small buckets.

Do 36 bump-and-run shots, 4 shots at each of the 9 stop zones.

From any pile, hit 4 shots to the first stop zone.

Do the same for the other stop zones, always 4 shots per zone, using the original ball setup.

Count shots that stop inside the right stop zone.

Add up how many shots were successful, and enter this number out of 36 attempts.

Put 36 golf balls into 3 groups of 12 balls. Spread the groups around the green between 1 and 10 yards from the edge and 5 to 30 yards from the hole.

Mark 3 landing zones in a straight line at the edge of the green, each 6 feet (2 meters) apart.

Hit 36 bump-and-run shots: 12 to zone 1, 12 to zone 2, 12 to zone

Use the first set of 12 balls for zone 1, the second set for zone 2, and the last set for zone

Keep ball positions and distances the same for the whole test.

Count each ball that stops inside the target zone as a success.

Add your total successful shots and enter your score in the app out of 36 attempts.

Set up 4 lines of 9 balls each, with balls 1 foot apart.

Place the lines on grass, 1 to 10 yards from the green, 5 yards between lines.

Mark two circles on the green around the hole: one with a 6-foot radius, another with a 15-foot radius.

Hit 36 shots, in two groups of 18 shots.

For the first 18 shots, aim for the small circle. For the next 18 shots, aim for the big circle.

Hit balls in order from any line, switch lines as wanted.

Count each ball that stops in the right circle as a success.

After 36 shots, count how many hit their target circles and enter your score in the app out of 36 attempts.
