Bigger paddle reach forward more even a stabbing reach to lengthen your stroke. Make sure your paddle exiting at your hips and you’re not lifting water. Most of your power is more towards the beginning portion of the stroke in my opinion. Hip rotation and locking you legs drives all the power from the paddle through your body and to the hull.
Entering and exiting the blades as clean as possible helps being efficient. Pushing and pulling evenly will give to more speed especially over a long haul.
Averaging 5 mph for 2.5 hours without aids of current and wind is a fast clip but doable.
Pull your rudder up but it usually may make your course longer in any kind of conditions.
If you really want to go fast you need to train at least every other day not once a week.
Wet sand to hull with 1000, 800 or 600 grit wetordry for the race.
The length of you paddle is? Do you feather the paddle?
Disclaimer old man self taught by doing it and watching YouTube. Lol I do have a decent pace. I think.
Pull the blade parallel with hull close as possible. Don’t bury the blade keep it within two inches of the surface.
Don’t cavitate the paddle. Pull boat to blade not blade to boat. If I take my biggest paddle and pull it so hard the water behind the blade is not there it’s not helping. Then I’m pulling blade to boat for the most part.
I’ll think of more in a bit on the race.
No hat in race and tight clothing. Size up the competition paddler and hull. Stay near them you need not sprint ahead and burn out prematurely.
Straightest course is the shortest don’t follow others.
Pace yourself and cadence. Practice the length of race you’re going to be in. Don’t get messed up in the turns with other competitors. Look for clean water with a good view. Don’t get stuck behind slower boats at the start give yourself good position .
Don’t be looking back it will take power from your stroke. If you get passed you’ll know soon enough and have to decide to keep up or on your pace.
I like paddle wax on the paddle even with gloves. Personal preference but try it if you don’t now.
Use mapmyrun or Strava to check your pace at short intervals.
Eat and hydrate properly two days ahead. Waiting for a race all year then getting sick because you may have got food poisoning somewhere would suck.
Keep blades in water as much as possible. Paddles that are to long prevent that and you’ll tire faster reaching higher to not submerge blade to much.
