You will find that these rallies are scheduled events and not just random gatherings. In fact, most of them take place each year and grow bigger and better every year.
Another staple at motorcycle rallies are poker runs. This is an organized motorcycle event where riders travel along a preset course, stopping at designated spots to select a card. At the end of the run, the rider with the best poker hand wins. Of course, the rules do vary from one rally to the next but if you are actually in charge of planning a poker run, then there are some things that you will need to know. First of all, the more organized you can be, the smoother it will go.
If you are going to have the rally on a public road, then you need to consider safety for both the motorcyclists and the general public alike. Therefore, speed should not be a consideration for the event.
Secondly, you should have a staggered start where the riders all start from the same location. The easiest way to do this is to subtract 3 minutes for every rally participant in the poker run from your total time, then set up the course to be this long at average legal driving speeds. There should be at least 5 checkpoints along the course where the riders pick up the cards.
Third, make sure that you have a good map of the area with all checkpoints clearly marked.
Fourth and finally, you will also have to consider whether or not to charge an entry fee and what the prize is going to be. Of course, this is also a great way to earn money for charity.
Something else that you can do is have a motorcycle fun run. There are usually several categories, including events for women and scooters. These have drawn crowds for years and lists can be found online if you want to find more information.
