That race didn't look too bad. I got good advice for mud racing. Get cheap foam like a sponge not styrofoam. Get some old fishnet stockings. Put the stockings on your fenders and slip the foam underneath it. Mud weighs alot after a while and you get fatigued. mud can't stick to foam it falls right off. Spray WD40 on other places you don't need to grip. We would even put a small block of sponge on our helmets. As you can see below its muddy races. Get a old pair of goggle lens and tape it to the front of your visor. This helps you avoid mud directly to your goggles by tilting you head down when you see a large mud puddle and a guy right in front of you. I use to do alot of endurance races. So we timed gas useage. We developed hand signals for need gas,change rider. Very vital in a race. we would also monitor riders. Wobbly head means the rider is worn out and needs to come in. When your worn out its hard to keep a good posture so wobbly head is the sign.
