Downhill mountain biking racing. Fastest run times.

Always ALWAYS head for the smoother path (obviously). Stay low, and keep your butt about two inches off the seat instead of more. Keep pedaling if you aren't in danger's way, and brake lightly when you are. Coordinate every move 10 seconds before you get there - it's hard not to get wrapped up in the "Oh damn! That's gonna slow me down!" attitude. Let it flow, but make sure the faucet's on full blast. When I rode, I had a knack for downhill, because I didn't worry at all about busting my butt or breaking any bones...I know that can be bad, but it will hinder you to a certain degree. Good luck!

145 mph on a Kawasaki GPz1100.  In rural Tennessee.  In 1984 so statute of limitations has passed.  To see how fast it would go.  It would go faster, i got scared.

I would say that its quite possible. Mountain biking is very physical but you can take it easy and not strain too much.

If you are truly interested in real mountain biking, go to a reputable bike shop and have them help you with size and fit.  I am an avid MTBr with the best bike for my body size and activity intensity.  It is worth the price and time if you are serious about this sport.\n\nI ride a Specialized Epic Disk and wouldn't trade it in the world.  Do NOT do the Walmart thing.  The components are terrible and the frames are not welded well enough for such an intense sport.  You can get a great bike from $300 on up.  Again, you get what you pay for.  \n\nWould you play football with cheap equipment??

Running, by far.  If I run for about 10 minutes I can burn about 100 calories.  It would take me 20 minutes to burn that many calories by biking.\n\n(Although if you are trying to get somewhere, it is definitely faster to bike!)

Decathlon. I have EVERY respect for EVERY COMPETITOR that completes 10 disciplines over 2 days. Great example being Daley Thompson's (GB) contributions over the years. Awesome.

I don't know if there's an official "world record" for that but it would be cool.\n\nThere are lots of "hill climb" races and fun rides around the world. Most of them are on pavement because when it gets really steep on dirt, your tires slip and you run out of speed.

D.\n\nHe would have to run 9 mph 2 catch up with/ overtake him. cuz Joe can run a mile every 10 minutes, so hes a mile a head of Ken before Ken even starts. So Ken has 20 minutes to run 3 miles. There is 3 sets of 20 mins in an hour and 3 miles per 20 minutes = 9mph! lol
