It's a high-speed new discipline for Buenos Aires 2018 and here's where you can watch it.
With a mass start, a tight 200m track and velodrome-like banked walls, expect expect plenty of jostling and exciting photo finishes!
The event was first seen on the Olympic stage at Nanjing 2014 YOG, where was well received as demonstration sport.
In each gender category 14 athletes will compete over 500m, 1000m and the 5000m elimination.
The winner of each race is awarded 14 points, second will take 13, third 12 and places 4-14 are awarded 11 points down to 1 point.
The final rankings are decided by the total number of points each skater accumulates over the three events.
Breaks are forbidden and the 200m world record (held my Spain's Joseba Fernandez) is 15.879 seconds - 3.3 seconds faster than Usain Bolt's world record!
Roller speed athletes often compete on speed skating on the ice.
Winter Olympic speed skating gold medallists who also competed on roller skates include America's Derek Parra (who was an 18-time roller speed world champion), three-time Olympic champ Martina Sablikova of the Czech Republic and the Netherlands Mulder twins.
Roller speed skating will take place at the Paseo de la Costa.
