This is an up-dated article on some of my better 2012 bike rides. It includes more detailed info on a smaller sampling of rides completed in 2012. It includes all the gears used on the ride, the average speeds both on the outgoing and return trips. The RPM rate has been put in that regards to the average speeds maintained on the rides.

The two bikes used are worlds apart. The road bike is light considering the cost and the rigid frame and proves a great solid ride quality. The mountain bike uses a full suspension design and has been set-up to provide a solid ride. The rear suspension is almost locked out to improve on road quality. If this not done, bio-pacing comes into play. That is the interaction of the bikes suspension to the pedalling action from the rider. Bio-pacing takes away from the energy of the rider and therefore the overall energy output of the rider. Based on the numbers given in the report, the mountain bike set-up provided a good match to the road bike. The extra weight is felt on the mountain bike but the use of the smooth 26 b y 1.95” tires help out in reducing the rolling resistance on-road riding. These small changes helped the mountain bike get into road bike speed range. The different gear combinations provided about the same overall gear ratios.

The set-up of the bike is very important. I have both these bikes set-up to be very close to each other. It allows the rider to have the feel on both bikes. The mountain bike has slightly higher so there is higher air resistance.

I have included other factors including the power output of the rider and weight loss as well. It gives good overview of the amount of work needed have any amount cycling needed gain any form of fitness over time. These facts are based on myself, being aged 51 years old at the time the rides where done. These numbers where figured out using an on-line cycling calculator.

The one of the measured factors missing from the file is my heart rate. I lack a heart rate monitor to get readings from my rides. Based on web based calculator I worked out that I was averaging around 140 beats per minute on the rides.

VO2 in the amount of oxygen taken in to power the body’s muscles. The higher the number is, the fitter the rider is as well. These numbers shown on the report where calculated using another on-line calculating program. “The general population aged 20 to 30 has V02 Max about 35 to 50 ml/kg/min, and this figure decreases considerably with aging.” This quote is from the web site that I used to calculate the number shown in the cycling stats. I think that or being 51 years old, I am doing ok for my age.
