Caleb Ewan's Sprint Position - Revealed through Kinesiology

First Race of the Season & First Win of the Season! 2014 Eagle Creek Fast Criterium Race Recap

If you follow me on Strava, you might have learned that at the end of the 2013 season, my Continental GP4000S tire blew up right after I made a solo attack and reached 33mph.  It sent me falling to the ground on my back and shoulder, gave me a concussion, plus strains and sprains at my neck, shoulder and abdomen.  The most dangerous aspect of my fall was that it was impossible to anticipate the tire failure.  The tread separated from the casing and caused an instant loss of traction- enough to send me to the ground despite travelling in a straight line.  Here are some pictures of my wounds.  Some of them went deep enough to reach my fat cells.  Check it out:
After 2.5 months off my bike to focus on rehabilitation, I was finally able to turn my head without my neck and shoulder going into spasms.  When I finally made it back on a bike, my legs and lungs hit the wall 15 minutes into the ride and forced me to stop.  Afterwards, my neck proceeded to go into spasms for hours due to the riding position.  
Continental never apologized or responded to my concerns about the tire.  My tire had no sidewall bubbling or cuts, and I actually checked my tire pressure with a tire gauge prior to its failure.  Despite riding on several pairs of Continental GP4000S tires for three years, I probably will never ride on them again.
Without my girlfriend of seven years, I wouldn't have survived the months healing and rehabilitating the injuries I sustained.  She patiently waited for me as I spent hours in the shower trying to tolerate the massive pain all over my body.  No one else could lighten the mood and help me laugh through the healing process.  The proof is in the pictures!  I was smiling in all of them thanks to her! :)

After riding on a defective Continental GP4000S, I decided to go tire shopping to find a better tire.  After riding on the Michelin Pro 4 for almost ten months now, including three criteriums, I can confidently say that its better than the GP4000S.  I've only had one flat which was caused by hitting a deep pothole.  I've always known the Continental GP4000S to produce flat tires from hitting decent pieces of gravel.  I remember worrying on several occasions that I would flat after hitting similar objects only to find that the Michelin Pro 4 survived without a scratch.  The grip surprised me the most about the Pro 4.  I wouldn't be surprised if an independent research company finds that the Michelin Pro 4 has better grip.  I've taken corners just as hard or harder than the Continental GP4000S this season.  I have yet to experience its limit around a corner.  I always thought that some sliding was normal in a tire until I tried the Pro 4.

As usual, I got lost trying to find the parking lot in Eagle Creek, so I ended up running late.  As a result I didn't get a chance to ride warm up or practice laps.  As soon as I received my number and had it pinned, I immediately had to line up at the start line.  Since I was also late to line-up, I had to start at the back.  I wasn't too worried since I knew we had 45 minutes to race.  Plenty of time right?

When the race started, Each lap only lasted about one minute and 44 seconds long.  I basically spent the majority of the race trying to move up to the front of the group.  It was hard trying to remain at the front due to the constant rotation of the group, and by the time we reached the final lap, I was about fourth place... from the back!

By the time we hit the bell lap, I was definitely panicking and almost accepted that I had no chance at even reaching a mid-pack finish.  That all changed about halfway down the lap.  The group hugged the inside of the road and left a moderate opening at the left.  As soon as I saw the opening, I knew that it was my last chance to reach the front, so I accelerated hard and bridged up to the front.  Once the five leaders were in sight, I noticed that I was approaching them quickly... while coasting!  Instead of coasting and slowing down to their speed, I started my sprint with an advantage and blew past the leaders.  When I crossed the finish line in first position, it didn't seem real, especially since I was almost last place by the start of the last lap!

Looking at the speed graph in the screenshot below, you'll notice three peaks.  The first acceleration was influenced by the group being aware of the last lap.  The second peak occurred when I bridged up to the front.  The last peak was the final sprint.  You'll notice that it took more speed to catch the leaders than it did to perform the final sprint!  Everything seemed to connect perfectly today!
Big thanks goes to Velocity Wheels and The Wheel Department for helping me replace my severely bent A23 Pro Build wheelset!  Your support helped motivate me to train and win the first race of the 2014 season!  Thanks guys!


  1. way to come back and start 2014 (hey year is almost over) been busy. Have spent last half of 2013 and all of 2014 rehabbing from a broken acetabulum. Your info early on in my rehab was a big help. Thanks for that. James B

    1. Thanks for the feedback James! I'm glad to hear that I was able to help out! What are you goals for 2015?

Kinesiological Approach To Bike Fit: Cleat Position

CLEAT POSITION:  There are four types of adjustments which can be made to a cleat.
Fore/ Aft:  FORE:  Positioning the cleat forward allows the ankle to move more freely, allowing for a smoother pedal stroke.  The trade-off is that this requires more ankle stability, calf strength and puts the rider at risk of developing quad dominance.AFT:  This position limits ankle motion.  This provides added stability to the ankle, allowing the calves to rest, but makes the rider prone to bouncy pedal strokes.  When switching from a forward cleat position to a rearward position, a lower saddle position is needed to compensate for decreased plantarflexion.Lateral/ Medial:  The goal is to spread weight evenly across the foot side-to-side.LATERAL:  Shifts weight towards the outside of the foot (small toe side).MEDIAL:  Shifts more weight onto the medial side of the foot (big toe side).  Limits the maximum amount of external rotation available before the heel strikes the crank arm.Rotation:EXTERNAL:  S…

How To Hold an Aero Position

There are climbs and then there are winds.  For many cyclists, riding into a strong wind can be more difficult than climbing, mostly because cyclists are required to reach a low aerodynamic position which can be uncomfortable, difficult or painful to hold.  Cyclists must demonstrate adequatehamstringandlower backflexibility to hold an aero position comfortably.  The flexibility needed to ride well in the wind can take time to develop, but with enough dedication and experience, anyone can become proficient at holding an aero position safely.  Here are some steps you can take to make holding an aero posture as comfortable as being on the hoods:

The worst thing a rider could do is force a low aero position and hope for the best.  With low back pain being one of the most frequent complaints among pros and recreational cyclist alike, the chances of long term pain- or injury-free riding are slim.  Develop the flexibility first, then shoot for the next lowest position yo…

Eagle Creek Park Cycling Grand Prix v2.0 - FIRST PLACE & FIRST PODIUM FINISH!

I can't even begin to describe how awesome it felt to have two dreams come true at once!  I always wondered what it would be like to be on the podium, but I never thought I had a chance at first place!

THE COURSE Below is a map of the course highlighted in blue.  It ran counterclockwise.  There were a few corners that stuck out to me.
Bottom right (corner #1):  This wasn't a very sharp corner, but the trees and brush made it difficult to see around it, so the group had a tendency to slow down and merge into a single line here.
Top right (corner #2):  This corner was very sharp, so oftentimes the group would merge into one or two pacelines, especially at higher speeds.
Top left (corner #3):  The inside half of this corner was covered by loose asphalt, so it wasn't an ideal or safe place to pass.  Pretty much everyone had to take a very awkward, wide line.  We could only fit about three abreast in this corner.
Bottom left (corner #4):  This was a very fast corner that led straigh…
