On Wednesdays we have one race which starts at 19:00.
On Sundays we have 3 or 4 races (depending on the time of year), starting at 11:00.
There is no problem with practicing during the racing… just let the race team know what you plan to do and they can advise upon which area of the water you can practice in. Or, better still, join in the racing!
The bar is usually open after racing.
