# Golf at 70 mph swing speed

A driver swung at 70 mph carries about 160 yards and totals 173 yards on the published tour table, with 97 mph of ball speed at a smash factor of 1.39. At the same fraction of tour speed a 7 iron carries 101 yards. The speed maps to about a 38 handicap on the handicap model and beyond the oldest band on the age model; 5 mph more is worth about 13 yards of carry.
