I have only done 3 XC races and about 6 short track. Our courses are closed for pre-ride day of the race. So get my number plate, go over the bike, ride about 30 minute warm up practicing sprints to open the legs. Visit the potty and deep breath. Get to the line about 15 minutes early. I am lucky at this point to not have stomach issues but with longer races I know pre-race food will be important. I am thinking about that....
