Torrential rain began falling during the early hours of Sunday morning and continued relentlessly throughout race day, creating conditions that some labelled as the worst ever seen at a motocross grand prix.
The organisers could do little about the appalling weather, but why were track-building diggers - Hyundai Heavy Industries sponsor the FIM series and have vehicles placed within camera shot at the side of the track - not used to at least try and release some of the worst standing water and scrape off some of the slop between motos?
Instead, track conditions started off as terrible and got steadily worse throughout the day; resulting in large pools of standings water, some almost thigh-deep in the bermed corners, and abandoned bikes littering the track - often buried up to their mudguards – before the steep terraced hill section became completely impassable.
The one and only MX1 moto saw home star Jonathan Barragan led the opening laps, before being passed by reigning world champion Ramon, who then pulled away from the rest of the field for what turned out to be his first ever premier-class GP win.
"I had a good start in third place and moved past de Reuver in the second turn and then took things easy," said Ramon. "I was running second when Barragan made a mistake in front of me and I took the lead. It was really difficult to ride the track and you had to concentrate hard because there were some really deep bumps and ruts, which you couldn't see because of the deep water.
"My riding was good and the bike was good and I won the moto which was good also of course. With the organisers cancelling the second moto it means I have won the overall, which is the first MX1 Grand Prix I have ever won and also the first GP win I have had in a very long time. I am really happy," he added.
Monster Yamaha's David Philippaerts crashed out in the early stages but quickly rejoined to climb up to an eventual second, while Ramon's team-mate Ken de Dycker crashed twice - once at the start and once again before the end of the opening lap - on his way to third.
Philippaerts's team-mate Josh Coppins was a solid third when he stalled the bike on a jump and eventually dropped down to fourth, ahead of Kawasaki's Estonian rider Tanel Leok. Marc de Reuver was disqualified as he started outside of his gate position.
All of which means that round one winner de Dycker still holds the red plate, now by seven points over Ramon. Philippaerts has moved up to third ahead of team-mate Coppins, while CAS Honda's Billy Mackenzie has slipped down to fifth after finishing eighth at Bellpuig on Sunday.
