Despite Loket being one of the oldest circuits on the Grand Prix calendar, its Grand Prix history isn’t as long as somewhere like Arco de Trento, Lommel, Teutschenthal or St Jean d'Angely. Still, all the way back in 1995, the first ever Grand Prix for the 500cc class was held at this old school facility.

The Czech Republic held many GPs since the 1960s, with Holice, Dalecin and Jinin being the favourites, but when Loket arrived on the scene, it pretty much became the most regular circuit to be used for Grand Prix motocross, of course still running the MXGP and MX2 championships in 2025.

That first World Championship race in the class 500 cc, which saw 65 riders from 3 continents and 19 countries, and this was a big opportunity for Loket. It was Belgian great, Joel Smets who first won at this grand old circuit, on his way to his first World 500cc championship.

Extensive modifications of the course and technical facilities were made before this World Championship race. Loket built new jury and press centre buildings, two underpasses for visitors, the paddock area was extended and also the starting plain was made wider.

In 1997 the premier class arrived in Loket, with the World Championship race in the class 250 cc, the attendance of 52 riders from 4 continents and 18 countries. Another Belgian, this time the GOAT of GP motocross, Stefan Everts won.

The track was further improved with two jumps, new tunnel was created from the paddock, foot bridge for visitors was built, tower for timekeeping and local radio in the finish area was restored, new electric cables and radio facilities were installed, in paddock new washing boxes were prepared.

In 1998 a new asphalt surface around jury and press centre buildings and on the neighbouring parking was made, also the first water distribution system around the track for watering for dusty weather was installed.

1999 the 500cc class returned to Loket, again Smets won, with an enlargement of the paddock carried out and in 2000, again it was the turn for the 250s to come back. A signalling zone for mechanics was set up, by the request of the promoter Mr Luongo, the finish was removed to the straight next to the jury building.

The triple GP arrived in Loket in 2000, with the three races of all three categories were hold on the same place in 5 racing tracks. Loket was among the seven countries, where only one race was hold. In 2002 another track shortening was made in terms of FIM rules.

adjusted waiting zone in terms of FIM rules, the new parking was built next to the entry to the area, extended banisters and new wooden fences for the public area limitation and constraints for riders’ safety, local watering system was enlarged.

for Word Championship competition the jury room was transferred into the building in the paddock. The press centre was extended into the former jury room as more media started to attend this triple class format. A new V.I.P. stand, new constraints along the track from the wooden fence pieces, new bulk-cargo tank for track watering was added.

In 2005 a new foot bridge for the public in the crossing of the track with the path, where riders arrive at the waiting zone, the track delimitation was set up in terms of valid FIM rules.

The format changed to World Championship in MX1 and MX2 categories, the course underwent fundamental changes before the races, mechanic zone was removed, in terms of valid FIM rules the track was shortened to todays 1586m.

A new guest parking and paddock area built, including water electricity and sanitary facilities, safety zones between the track and public area according to FIM rules extended, track watering system completed including new water borehole in the storage tanks area.

Over the last two decades, Loket has remained the only facility used for Grand Prix in the Czech Republic, and it remains one of the toughest circuits on the calendar and as old school as you can get.
