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 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.

  • Racing in North Carolina

    I raced a 10 mile Time Trial on July 23rd at Lowes Speedway. I finished 2nd in the Cat 4 group with a time of 21 minutes and 24 seconds. This was also good enough for 17th overall. So I felt like my fitness was pretty good. This weekend was a big race weekend in Charlotte. There were Criteriums Thursday-Sunday around the area. There was also a Team TimeTrial on Thursday.

  • 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.

  • 2012 Dillworth Criterium

    The 2012 Dillworth Criterium was my first road race of the year.   Dillworth isn’t one of my favorite courses.  I find it to be a challenging course with a long, steady climb on the front stretch, plus it’s usually the my first road race of the year so my body isn’t used to the effort required in a criterium.

    My race started at 2.  I arrived a little early to catch the end of the Cat 4/5 race to see my friend Mike Levine finish up.  After that, I rode my bike around for about 20 minutes to get the legs going.

  • 2012 Elite, U23, Juniors & Paralympic Road National Championships – Day 4

    Saturday (6/25/12) was Day 4 for Chester and I at the 2012 Elite, U23, Juniors & Paralympic Road National Championships. Today’s race was the 72K Road Race which was divided up into 3 laps.
    Our race was at 8 and held on the Fort Gordon Military Base. Since our race started at 8, we had an early wake up call. Chester woke up at 4:30 excited to get going. I rolled out of bed around 5:15 and started getting ready. We managed to roll out to the truck around 6:30 and were at the race venue at 7.

  • 2012 Brushy Mountain Training Ride 5

    4/4/12    Andy and I made it up to Brushy Mountain yesterday.  It was my 5th time to Brushy this season.  It’s always fun to start the season of with a bunch of trips to Brushy to get into shape.  I set a PR on the last trip and this weeks trip was just a steady state ride, especially with a VO2 test on Friday and the 6 Hours of Warrior Creek on Saturday.
