We are looking forward to seeing you at the 2015 Orange County Triathlon. This USA Triathlon sanctioned event will offer the new Super Sprint Distance this year.
The Hudson River current aided swim described.
The mighty Hudson River is a 315-mile (507 km) river that flows from north to south primarily through eastern New York in the United States. The river originates in Essex County, New York, flowing through the Hudson Valley, then draining into the Atlantic Ocean at New York City and North Jersey.
The Hudson River is classified as a tidal estuary which is defined as a semi-enclosed body of brackish water – a mixture of salty and fresh water. Strictly speaking, the Hudson River by Manhattan and northward past the Tappan Zee is normally an estuary and typically has more ocean water than river water in the mix. Brackish water can actually work its way about 70 miles north of NYC to Poughkeepsie and surrounding areas.
The Race Directors of the Orange County Triathlon study the Hudson River and its tides and currents to determine the ideal time to hole the event. So in planning the Orange County Triathlon, the Hudson River actually picks the date for us.
Ebb, Flood and Slack water are all terms that define the rivers daily movements, and are all studied on the day of the event to determine the best time to begin the swim. The Hudson River floods and recedes several times a day producing high and low tides. One can see the results of high and low tides just by watching the coast of the river, and how it changes in height over the course of the day.
A flood current is during a high tide when water moves landward or up the river causing the river to rise. An Ebb current is during low tide when water recedes seaward. The strongest flood and Ebb currents usually occur before or near the time of high and low tides. The weakest currents occur between the Flood and Ebb currents and are called slack tides.
Typically we start the event at the beginning of an Ebb current. These Ebb currents can flow up to 1 plus knots per (1.151 miles per hour, approximately) and can carry a swimmer much faster than swimming in slack water (still water, like a lake or pool) resulting in much faster swim times and less effort produced by the swimmer. This is why our swimmers produce personal best swim times at our event.
