When the friends pass the 20km mark, the clock says 2:35:15. When Leo, Nico and Kees have passed the finish line, the clock says 4:13. This would mean that the group took about 1 hour and 38 minutes for the remaining 22,195 km. This is a pace of 4:25 (m/km), which is equal to 13.6 km/hour or 8.4 miles/hour. This is quite an impressive pace, given the distance, their age and their physical appearance.
