Buttboard is very narrow, so very unstable.	People don't know (and don't care) the difference between streetluge and buttboard. The butt is more like a toy than a "speed weapon engine". But it's the same pleasure with the same risk. Riders know them self that if they are crazy, they won't stay alive 1year. And some of them understand, after a short "trip in emergency" that buttboarding is a serious sport where you need lot of concentration, training and technique. Even if buttboarding is "slower" than streetluging, the average speed is 50mp/h but you can easily reach 60mp/h, it depends on the road. I started buttboarding in 2005 because of the new competition format. Instead of 4 riders for each heat, it's 16 riders on the same line: Crazy. ( I will speak about it later down) It's much easier and faster to build a buttboard but there are many rules about the butt compare to the streetluge.
16 riders in the same track. Exiting and scary.	Lot of smoke before the hairpin when riders are slowing down.	Too fast in a corner. First part of your body to absorb the choc; your ankle.

Butt SC8: Perfect and nice work.

You can buy your buttboard or build it yourself. Compare to streetluging, there are many rules if you want to build your butt. There is a maxi longer and width for the board. The weight maximal is 5 kilograms, 4 wheels maxi with a 70millimeters diameters maximum too. Every rider is almost using the same engine. We use to say that streetluging is the Formula 1 and buttboarding the rally of the gravity.

Such tiring for your abdominal muscles, even more in hairpins.	Alright! So how does it work? Easy. You lay on your back with the feet forward. There are no handle, like on a streetluge. You grab directly the board. You have to be careful because you fingers are close to the wheels. How to stop or slow down? Easy too! With your feet. You have to sit on your butt first and after, you will put your shoes flat on the road and you push. But don't forget to stick tires under your shoes. Otherwise, it will take 1 minutes before you "kill" them. In the corner or hairpin, never stand up when you want to turn. It's the beginner mistake. Your back is moving to the left to the right to make your butt turn. In the hairpin or very short turn, you have to put your outside hand on the back of the butt. Why? Because your body will be a lot inside the corner, and the back of the butt outside. So, you will use your hand to keep the back wheels on the road. Otherwise, the back will slide. The bad thing where you butt is the wobble. When you are too fast, your butt is going to move from the left to the right very quickly. You need a good technique to stop the wobble before you flip over.
Try to stick your front concurent to get his sleepstream.	Watch out !!! fingers are very close to the wheels when you slow down.	Always in contact to be ready to pass and win 1 rank.

Monsieur "Tournibroche" on the pole position. Be carefull, 15 riders are going to push your bum.

The rules? There is a downhill French Federation for gravity sports. There is a French Cup with 5 or 6 events everywhere in France during the summer. We also have an international circuit: IGSA (International Gravity Sports Association) with lot of contest in USA, Brazil, Sweden, South Africa and Europe. This is the official competitions. There are also lot of non official competition too. If you want to register, you have to py an enter fee and you must have a leather jacket, helmet and back protection for racing. You need a licence for the official events. It takes 2 days to organize an event. Trainings and qualifications the first day, and the boarders the second day. During the qualifications, they keep your best time. If you are in the top 16, you are going to fight, otherwise; No!!! This is the difference. It's not going to be 4 riders for each heat, but 16. The GP, Grand Prix. There is a pole position for the best time, second position, etc. The last one is 40 meters behind the first one. So? How the last one could win? We usually make 4 or 5 runs with 16 riders and after each heat, you are going to take your arrival position on the start line.

Go! Let's have fun.	The starter is giving the start:" riders ready? In the 5 seconds (he has 5 seconds to say go)...GO!!! Sited on your butt, you push with your hands to take some speed. There is less pressure than streetluge, because you know that you have 3 or 4 heats to win ranks. It's very exiting to see and race because there are many attacks, many crashes, many injure at the end of the race. (Why you push me… why you did this…etc, so fun, I love) I say "fighting" when you race, but they are rules. You cannot change your trajectory to cross others riders way, and you cannot make "crazy attack". Judge and usually riders check out the rules them self.
Adri and I... "you know Adri, you will be "dead" in the second hairpin"...lol.	All together in the corner. I have to put my legs over Schrek.	Already 2 riders in the hairpin. doesn't matter, I dive inside and pass. Yeah!
