JOIN USFormula One's record 22 race calendar for 2014 is 'beyond the limit' for teams but looks likely to be trimmed before it becomes definitive, according to Red Bull team principal Christian Horner.
Three races on the calendar released last week have asterisks against them — South Korea, New Jersey and Mexico — and the prospects of the first two at least have been called into question.
Most teams are reluctant to go beyond 20 races, mindful of the added expense and the burden being shouldered by key staff such as engineers and race mechanics who cannot easily be rotated.
This year's championship has 19 races, with the record standing at 20.
"I think we all recognise that 22 races is beyond the limit, the strain that it puts on the team and the entourage that follow Formula One," Horner said ahead of Sunday's Korean Grand Prix.
"For me the ideal number is 20, that I think is saturation point, but I can understand why he (Formula One supremo Bernie Ecclestone) is pushing to get more venues,” he added.
