Where have I been for the last couple of years? Have I been living under a rock? Why didn’t I know what Sharrows were until just yesterday? I’ve seen the chevron looking markings on the road in one section of my commute but until yesterday I had no idea what they meant. I’m a dunce! In my defense, the markings I have seen in Oceanside haven’t been there for two years but at least 6 months!
So what are Sharrows? Below is an image of one. What are they used for? Here are some examples.
The stated purposes of the shared-lane markings used in California were to:
- Assist bicyclists with lateral positioning in a shared lane with on-street parallel parking in order to reduce the chance of a bicyclist’s impacting the open door of a parked vehicle;
- Assist bicyclists with lateral positioning in lanes that are too narrow for a motor vehicle and a bicycle to travel side by side within the same traffic lane;
- Alert road users of the lateral location bicyclists are likely to occupy within the traveled way;
- Encourage safe passing of bicyclists by motorists; and
- Reduce the incidence of wrong-way bicycling.

I did a partial commute this morning. Partial commute means I take the train part of the way and ride part of the way. It almost splits up perfectly 35 miles on the train and 30 miles on the bike. It was just getting light out as I pulled into a Starbucks. Once in side a gentleman approaches me and says “Your reflective stuff works. Man I can really see you a mile away” That’s good to know since I leave the house before 5am on my commuting days.
Thank you Nathan Sports for the gear.
I really like the terry cloth ankle bands from Nathan. They are really comfy and very reflective!!
My wheels have reflective tape on them. I don’t worry about the “uncool” factor of having reflective tape on my wheels or my bike. I have a family and I need to get home to them. My I present to you Chloe, my Cervelo Carbon Soloist.
In the last two weeks my 4 1/2 year old son has been asking for me to play Time when we are in the car. Often he will suggest “AGAIN!”. LOL! I think maybe he likes the alarm clocks at the beginning but I also catch him mouthing the words. I decided to look them up and study the lyrics and interpret them for me. It is interesting what they meant to me. For years I have heard this song but never really listened. Take a look now at the lyrics and see if they have any special meaning for you.
Ticking away the moments that make up a dull day
You fritter and waste the hours in an off hand way
Kicking around on a piece of ground in your home
Waiting for someone or something to show you the way
Tired of lying in the sunshine staying home
to watch the rain
You are young and life is long and there is time to kill today
And then one day you find ten years have got behind you
No one told you when to run, you missed the starting gun
And you run and you run to catch up with the sun, but its sinking
And racing around to come up behind you again
The sun is the same in the relative way, but youre older
Shorter of breath and one day closer to death
Every year is getting shorter, never seem to find the time
Plans that either come to naught or half a page of scribbled lines
Hanging on in quiet desperation is the english way
The time is gone, the song is over, thought Id something more to say
Home, home again
I like to be here when I can
And when I come home cold and tired
Its good to warm my bones beside the fire
Far away across the field
The tolling of the iron bell
Calls the faithful to their knees
To hear the softly spoken magic spells.

20 minute Peak Power from my morning commute. Weight 152 lbs or 69 kg
Average Power 244 watts / 69 kg 3.53 w/kg
Normalized Power 254 watts / 69 kg 3.68 w/kg
Look at my wattage from last night’s commute. What I would like for you to notice is that my Average Power was up a whopping 24 watts but my Normalized Power was only up 5 watts from 249 to 254 watts. Why is that?
Let’s look at Normalized Power :
TrainingPeaks uses a special algorithm to calculate an adjusted or normalized power for each ride or segment of a ride (longer than 30 seconds) that you analyze. This algorithm is somewhat complicated, but importantly it incorporates two key pieces of information: 1) the physiological responses to rapid changes in exercise intensity are not instantaneous, but follow a predictable time course, and 2) many critical physiological responses (e.g., glycogen utilization, lactate production, stress hormone levels) are curvilinearly, rather than linearly, related to exercise intensity, By taking these factors into account, normalized power provides a better measure of the true physiological demands of a given training session – in essence, it is an estimate of the power that you could have maintained for the same physiological “cost” if your power output had been perfectly constant (e.g., as on a stationary cycle ergometer), rather than variable. Keeping track of normalized power is therefore a more accurate way of quantifying the actual intensity of training sessions, or even races.
In other words, when you apply power to the pedals it takes time for your body to react and when it does it reacts on a curve not in a straight line. Normalized Power takes this into account.
Or like my friend Sushi Joe says it “NP = the power you could have put out if you kept the effort as steady as possible. “
So back to my ride from last night. Notice how the POWER line is more erratic with rollers and traffic signals.

Compare it to this morning’s ride was not as variable the power was more consistent so the Normalized Power only increased by 5 watts from 249 watts to 254 watts.
