Map of the climbing route with the X and Y coordinates of the 40 holds.
Fig 2.
Decision tree to define the visual strategies during the route preview.
Fig 3.
Number of fixations on each hold indicated by hold color.
Red indicates lots of fixations and blue indicates few fixations. This ‘heat map’ shows that holds 7, 9, 10, 16, 18 and 19 received more attention, while holds 33–40 received little attention.

Mean (M) and standard deviation (SD) for the eight variables distinguishing the four clusters.
Table 3.
Mean (M) and standard deviation (SD) for climbing duration, climbing fluency (jerk coefficient) and the relative duration of the different activity states during the climb for the four clusters.
