This is the 4th installment of the War on the Shore Criterium Race, Sunday July 28th in Southampton. As always, to put on this great event right here in Southampton, we need help. We are reaching out for volunteers for setting up and or tearing down equipment, marshaling corners, registration, kids race, podiums, sweeping corners. You only have an hour to give? We’ll take it. Great view, great racing, free lunch for volunteers. What better way to spend your time and have some fun! Just give a shout out to Brett at Martin’s Bike Shop to let us know you’re available to help out. Many thanks!
The Participant Guidelines document has been updated and can be viewed on the Documents page.
I bought a Velocomp PowerPod BLE power meter for my bike and promised Brian of The Forks Bicycle Shop that I would let him know how it worked out.
Traditional power meters measure Direct Force (DFMs). They have strain gauges built into either the pedals, cranks or wheel hub. They measure exactly what force you are applying through the drive chain and display it on the head unit in Watts. They can cost as much as a $1000.
Velocomp’s PowerPod relies on Newton’s Third Law. If it knows what forces are opposing you, then it knows what force you are applying. The opposing forces are due to: Wind resistance, gravity (up a hill), rolling resistance and acceleration.
It mounts under the handlebars, with no other physical connection to the bike. It measures wind speed, through a port in the front, and inclination and acceleration. It also needs to know your road speed.
So, to set it up you pair it with an ANT+ or BLE speed sensor and to your “head unit” (Garmin, ELEMNT Bolt, etc). Then you do a short out and back calibration ride. This is mainly for it to figure out the inclination adjustment – because you mounted it only approximately horizontally. During the calibration ride, instead of actual Watts, it displays 1-50 for the “out” portion and 51-100 for the “back” portion of the ride. After that it displays actual power.
That would be enough for rough power measurements. There are factory defaults for rider’s weight, bike weight, riding position, tire size etc. But you can fine tune all of these using free downloadable software (Mac and Windows). Connect the unit via the USB cable and you set your actual weight, that of the bike, whether you ride mostly with the hands on the brake hoods or drops, and lots more. You can save this configuration data into the PowerPod for up to five different bikes, so you can easily move the unit from bike to bike.
The same software displays a lot of other data for each ride you have logged. For example, it plots road speed and apparent wind speed together (the white and blue respectively) You can see where I rode into the wind (blue is greater) and after I turned around I had a following wind. The altitude profile shows when you were coasting and braking.
I’ve been using a smart trainer with Zwift and FulGaz all winter, so I now have a feeling for what power I’m generating. I’ve also done regular FTP (Functional Threshold Power) tests as part of a 12 week climbing program. After doing the fine tuning described above, I think the PowerPod is quite close to a DFM.
I was amazed how quickly the Wattage goes to zero when I stop pedaling. It “knows” that for the combined weight, slope and head wind I don’t need to apply any other force to achieve the speed I’m coasting at.
My version cost $299 US. (Online from the manufacturer. Local bike shops don’t carry it.) There is a slightly cheaper one that has only ANT+ connectivity. Mine has BLE too. Some Garmin speed sensors are not compatible. I’m using Wahoo’s magnet-less sensor around the wheel hub.
For about $50 you can buy a software license to unlock pedal stroke analysis. For that you need a cadence sensor on the crank (not on your shoe).
There is also the AreoPod that helps a rider perfect their aerodynamics. But this requires a DFM.
Toronto lawyer and bicycling advocate, David Shellnut has recently published an article advising cyclists on what to do in the event they are involved in an accident. Very interesting read.
The OSCC executive have reviewed the Risk Management Plan as it pertains to Tri-Bikes. Although the Risk Management Plan states NO Tri-Bikes on group rides, we have agreed to allow them if you do not have an alternate road bike. The stipulation is you must not ride on the aerobars in the pack and must have easy access to your brakes at all times. It is not the intent of the OSCC to dis-allow participation on our group rides, however given the diversity of the group, e.g. skills and ability, safety is of utmost importance.
Our ride leaders have set the dates for the 2019 group rides and TTs.

As part of National Coaches Week, the Ontario Cycling Association is
proud to announce the launch of several initiatives focused on
increasing female cycling coaches in Ontario. These initiatives are
supported through Quest for Gold funding administered by the Coaching
Association of Ontario.
* SUBSIDIES FOR COMPLETION OF NCCP COURSES: Female coaches will be
eligible to apply for up to 70% subsidy for completion of courses
leading to Introduction to Competition certification
* COACH PROFESSIONAL DEVELOPMENT SUPPORT: Female coaches may apply for
support to assist with travel and other expense to attend a camp or
competition under the mentorship of a Team Ontario, Team Canada, or
other high level coach
* WOMEN’S COACHING CONFERENCE: The OCA is excited to announce the
hosting of the Women’s Coaching Conference on December 9, 2018 at the
Mattamy National Cycling Centre. This one-day conference will include a
series of presenters covering topics applicable to today’s cycling
athletes. Workshops will be delivered both in-class and through
