Video Description: From cyclists to race cars, the motion of an object is determined by the sum of the forces acting on it. Those forces have both strength and direction and they can be observed and measured to predict future motion. Watch how an aeronautics engineer works with Newton’s three Laws of Motion to test the best posture and helmet for a cyclist in a wind tunnel.

  • Race 2 – 2012 Charlotte Summer Mountain Bike Series

    The first official race of the Charlotte Summer Series Mountain Bike Series hosted by Charlotte Sports Cycling was at North Mecklenburg Park.  I took the Cool Breeze Van down N. Meck and set the tent up.  With this being the first race and at a relatively easy course, the numbers were impressive.  I’m betting Neal had over 150 racers.  The Cool Breeze/Trek Bike Store team had 12 racers!  A great turn out!

    I decided to race the Super Sport class for the summer series.  I considered the Expert class but don’t have a USAC expert license so I couldn’t sign up for the extra length required of the expert class.   We had 12 racers in the Super Sport class which is a great turnout for this class.

  • 2011 Ion Smack Down – Charleston, South Carolina

    I headed to Charleston, SC for a weekend of criterium racing.  I left on Friday, April 15th after going for a 25 mile ride in Mooresville.  We arrived in Charleston around 6:30 and Leah and Neal arrived shortly thereafter.   We all went to dinner and celebrated Neal’s birthdays. 

    I woke up early (5AM) Saturday morning to help Neal set up the crit course. We arrived at the venue around 5:45AM and started unloading his trailer to get the stage and truss setup.  Things were pretty nervous as the forecast was for major winds and rain.  We got everything setup with 15 minutes to spare.  The good news was that the rain held off and the course started drying up.

  • Race 2 – 2011 Charlotte Winter Short Track Series

    This past Sunday was the second race of the Charlotte Mountain Bike Winter Series. I was hoping for a better result than I had the  previous weekend. The weather was colder but it was dry (finally) all week. I got to the course around 10 to watch Lexi (Jasen Taylor’s  little girl) while he raced. Watching them race got me a little excited to get going and the good news is that the riders were staying  dry and mud free.

  • 2012 Elite, U23, Juniors & Paralympic Road National Championships – Day 2

    Today (6/21/12) was Day 2 of our trip to the 2012 Elite, U23, Juniors & Paralympic Road National Championships.  Today’s event was the Time Trial National Championship.

    Chester and I didn’t start until 3:15 so we were able to sleep in – until about 7:15…which was late for me.  We got up and had breakfast, ran an errand and then came back to the hotel room.  Our plan was to stay cool, get hydrated and then to get to the venue around 1pm to get our race numbers, check out the start and warm up.

  • Race 4 – 2011 Charlotte Winter Short Track Series

    I was hoping for a good day on the bike after last weeks successful race.  The racers were sure that the course was going to be a wreck as it rained pretty much all of Friday and most of Saturday morning.

    I was able to get to the course a little earlier than normal and actually get about 25 minute warm up with some sprints to get the legs going.  They were a little sore because I reffed two lacrosse games in Chapel Hill on Saturday.  But I did feel good in the warm up.

  • In Shape?…Maybe Not!…

    It’s been a long season so far. I don’t know if I’m in good shape or not. I participated in the Charlotte MotorSpeedway Time Trial on June 9, 2010 in the Category 3 group. I got to the track early enough to register, get a start time assigned, and then have a solid warm up. I don’t like riding a trainer so I warmed up on the small track inside the big track. I immediately noticed two things….people warming up on TT bikes not using their aero bars (which I can’t understand) and the wind. It was pretty obvious that we had a big headwind going all the way down the home stretch between turn number 4 and turn number 1. It was the most wind I had experienced in the 3 years that I’ve been doing the TT.
