The OC&C Ringvaart Regatta is a 100 km long rowing regatta. The race starts in Leiden and goes over the Kaag to the North. It goes around the Ringvaart canal back to Leiden to eventually finish in Delft. The full route can be seen in the picture below. It was first organised in 1976 to celebrate the 100^th anniversary of D.S.R.V. Laga. The first time only three boats participated in the race, but nowadays over 150 boats start the 100 km challenge. This year the OC&C Ringvaart Regatta takes place on May 29^th.

Along the route there are 5 stops with toilets and water supply. The distance between each stop is around 20 km. The last stop is situated at 85km in Leidschendam. Here all the boats will be lifted out of the water by volunteers, since there is a lock that cannot be passed. After a stop of 30 minutes where rowers can get a massage, the last kilometres can be rowed to Delft. The finish location will be festive with music to celebrate the success of finishing the OC&C Ringvaart Regatta.

The last 500 meter will consist of a sprint competition. The times of all boat numbers will be converted to a percentage of the best time in that boat number, the boat with the lowest percentage wins the sprint. The same is done for the overall winner of the OC&C Ringvaart Regatta.

Due to the rough water at the big lake the Kaag, it is possible that the race cannot take place on May 29^th in case of extereme weather conditions. If this would be the case, the race will take place on the 12^th of June.
