How the day Goes:

Our events usually start at 10:00 am, with a riders' meeting at 9:45, by the Registration desk.
During the riders' meeting the loop is described. The local landowner or BLM personnel are thanked, and what section you will start on and other course and safety information is discussed. Awards from previous events given out, and other general business discussed. This is a great time to catch up with your mates.

After the riders meeting, the event starts and you ride to your designated section to begin your trial. The loop is marked by pink ribbons about every 20 yards or so.

When you arrive at your section, walk it. Figure out your strategy, which obstacles to avoid, and where the section boundaries are. Cards will be placed indicating where your specific line is. If you have a question, the section checker will help to point out your intended line. Wait for the checker at your section to wave you into the section before riding it. The checkers have volunteered their day to staff the section; be nice to them.

Get your score card punched after your ride, and follow the loop to the next section.

After the first loop (and every subsequent loop) check your card to confirm you have not missed any sections. Hand in your card to the sign-up table, get a fresh card and start the next loop.

After three loops, marvel in the feat of completing your first trial. Wear your grin all the way home. Welcome to the family!
