This endurance race is around 6 miles (50 min) long and passes through the Tamar, Tavy & Lynher rivers. As a very rough estimate Mens crews can expect to finish in 40 – 50 minutes and ladies crews under an hour. Tide is a big factor on this race, both mens and ladies crews will start with an ebb tide against them in the channel, the course (See chart below) follows this deep water to the first mark before turning to Starboard into the shallower mouth of the Tavy and the bridge. Rounding the second mark to port a short leg will take you to the third mark which again you leave to port before turning with the tide and heading back to the bridge. The bridge is about two thirds of the way to the fourth and fith marks (At the mouth of the Lynher) which you round to port before turning back into the tide for a final sprint back up the river towards the bridge. The tide will be stronger for the mens teams than the women as they set off mid tide.
Please note: This is all estimated times and distance and assumes the same course as 2007.

Note the massive variance in speed over the ground mostly due to tide. The 2007 race had similar tides to this years race.
