    RJ's paulflexes just posted this video of the Slaughterhouse Trail to YouTube:

    ( Let the video fully load first and click it to full screen for best effect!)

    Google Maps says the Slaughterhouse Trail is 1.4 miles long and takes 18 minutes to ride on a bike while dropping 351 feet from 1745 feet elevation.

    Thus, the Google-recommended speed is roughly 4.67 mph.

    Of Paul's 8:20 minute video, 30 seconds of it is on the main highway, not the trail. So Paul did the trail in 7:50 minutes.

    Paul's bat-outa-hell speed is roughly 10.7 mph, over twice as fast.

    It's pretty much a downhill decline throughout the entire bike path.

    I ride a bicycle almost daily and whenever I calculate a new destination using Google maps I easily cut down the estimated time that Google provides. Even at what feels like a leisurely pace for me, I always arrive at my destination much sooner. Those time guidelines must be for overweight very slow people.

    The only way I could ride my bike while going downhill at 4.67 mph is if I had my brakes slightly pressed. This is hardly impressive.

    Well, Google's estimate was used only as a reference for the speed Paul did, which undeniably is pretty bat-out-of-hellish on such unruly terrain! I suspect that Google's time algorithms are most accurate for flat land and don't do downhill or unwieldily terrain all that well. For the flat land I've found their estimates pretty accurate for an nice, leisurely, don't-push-it rate of pedaling (politically correct for don't-upset-fat-people), but rates which one can easily exceed if one wants, a mile on the flat easily accomplished in 2 to 4 minutes.

    Shit, riding on rough pavement riddled with ruts and potholes in most older northern US cities can easily count as riding on unruly terrain.icon_razz.gif

    If you ever visit this side of the pond and wanna ride, hmu. I ride almost every single day (no car), and ride trails as often as possible. In fact I recently quit my job as a contract pilot, and am going to work this week as a bike courier in downtown Miami...which is conveniently close to a great trail system just across the causeway on an island (Virginia Key MTB trails).

    Yes, riding is my life lol

    I can attest to that. You've met me up here in Wilton Manors, having pedaled from Hollywood, Florida and then back, just for that.

    As for Virginia Key, funny story. In the early or mid-70s I was down here on one of my motorcycles. If it wasn't the BMW then I think it was the Suzuki 750. And exploring around, and looking for a beach to cool off, I stumbled onto Virginia Key off the causeway.

    I used a public changing station on the beach to take a shower after swimming, and some guy was evidently cruising me. I got nervous in the shower and got a boner. He laughed at me so loud, I was just mortified.

    Later I went back to my sister's home and mentioned where I'd been that day, including Key Biscayne and Virginia Key. She said to me in a shocked voice: "Virginia Key??? That's where all the gays go!" I think she used that term. "And they swim nude, too!"

    Well, I told her the beach was almost deserted on a weekday, and I saw no one nude. Not wanting to mention the possible cruising episode I said I saw nothing unusual. "Well, don't go back there," she warned me. "You've got your Army Officer's reputation to worry about."

    Years later she told me our parents had confided to her that I was gay, right after I joined the Army. Their great fear was that my fellow soldiers would kill me, when they found out I was gay, more than any risk from the enemy in Vietnam. Never happened, I actually had a successful and uneventful 25 years.

    My going to Virginia Key must have really proved it in her mind. I just wish someone in the family had told ME all this back then. Would have saved me a lot of grief and lost opportunities. LOL!
