More than 20,000 spectators travelled to the hilly venue and traditional site of the Czech stop of the Grand Prix calendar, where they saw East Hoathly and Heathfield star Mel Pocock continue his domination of the world of motocross.
The fast and undulating layout provided its usual mix of stony hard-pack that forced a test of throttle control, caution, bravery through overtaking and precious little traction.
Under sunshine and high-ish temperatures, Mel again was able to shine in the European MX2 Championship, and posted a 2-1 scorecard in both motos to claim his fourth win from four events.
The 20-year-old had to concede his 100 per cent moto record to Maxime Despray on Saturday after a mistake caused him to lose the back wheel of the French youngster but Pocock fired back Sunday morning with a superb display to hold off Tim Gasjer and Jeremy Seewer to take his moto haul to seven from eight.
Mel now has a 39-point advantage in the standings with only meetings in England, Holland and Italy remaining.
Mel said: “It’s great to win four from four and keep that overall streak alive. I’m a bit disappointed I missed out on the win on Saturday but Maxime was going really quick.
“It is not my ideal surface as a rider; I prefer mud or deep sand or berms to hit! Maxime got away from me in that first race and I made a mistake that cost me the race.
“I backed down the speed a bit to make sure of the points for second. Today he made a small mistake and dropped the bike, so I had the lead and made sure I rode error-free ahead of Gasjer.
“It was a hard weekend but I made it work for me. I had to learn out there.”
Mel next rides at Matterley Basin, Winchester, where he will be defending his 39-point lead before a fired-up British audience.
Mel is a former Heathfield Community College student.
