The rules are simple: a maximum of seven clubs that are carried, the number of strokes added together with the duration and becomes total results. A deflected ball may be replaced in the escape line with a duty blow.
Kristoffer Lindén's record is 80 strokes and just over 57 minutes, ie 137, but far from the most international.
The world record is from a competition in Australia 2016, 77 strokes in breathtaking 31 (!) Minutes, a total of 108.
This summer, a couple of Swedish competitions, Allerum this weekend and Oskarshamn, will be decided in July and in August an SM at Täby Golf Club. For the last gold, 75 strokes were required in 52 minutes. There are also international tours, an annual World Cup and British Open.
