It's a good rule of thumb for this and all races to KNOW THE COURSE. Don't add unnecessary distance! After taking the big loop to turn around I was told the turn around is the much smaller loop with the cone (which should have been my first hint) :-)

Thanks Mark, Nola, and everyone involved!

Yes and the shorter loop makes it interesting on a fixed gear. Pedal scrape vs MPH calculations fly thru my brain as I enter in to the turn..

Thanks Mark

I'll let it slide this time!  LOL

And Mike, it was fun chasing down your son.  HE pushed ME to go faster!

Or try to take it at ~25mph like I did in week 1 - road rash is still healing...

Thanks again for all the hard work from the volunteers.  I was hoping to beat the 24:00 mark last night, but the official timing had me a bit slower than that.    My Joule 2.0 had me crossing the line at 23:55 or so, but I must have been off by about 10 seconds from the official time.  I suspect that my Joule isn't starting right away when I leave the starting line...

Last year, my cyclocomputer (Garmin 305) was always a very good match for the official time.  This year, I have been using a Joule 2.0, and there must be some start-up lag before the computer starts counting right off the start line.   If anyone else is using a Joule computer, have you noticed a similar effect?

My experiernce with the Joule is that it does not collect accurate split times when you try to start it from a idle period (such as waiting in line for your TT start).  In fact, I have had several experiences where the downloaded file did not record the interval when I attempted to start it from a standing start preceeded by an idle period.  For mass starts, I resolve this by keeping the computer active between warming up, standing on the line waiting for a start, and the actual start whislte by occasionally scrolling through the fields..  Then, I roll a few feet to get the computer going before hitting the split buttons.  Can't do that in a TT though (unless you want to roll two pedal strokes, sit down, coast while you take a split and then start up again).  So, to resolve this for TT's, when I download the file, I choose not to merge the files (I use the CycleOps software that came with the Joule computer/Powertap wheel).  If I download the TT file separately from the rest of the workout, it does show an accurate time....or, at least a time that reflects how much time it takes me to get off the aero bars and punch the buttons to record a split time.

I have been re-setting the Joule just before rolling into the start position - this might be causing my issue.  I like to use the "Ride Time" function while riding the TT, but I think it might not be starting up at the exact time that my forward motion starts.

I agree with your experience of being able to download the file later and record the points where the effort begins and ends, creating an interval for the entire TT.  This works pretty well after the fact, using the PowerAgent software, but isn't very helpful for capturing an actual split time at the turn-around, or when crossing the finish line.

^^^ this. I have a Garmin 500. It has an autostart feature that sounds a lot like what the Joule is doing. When autostart is on it stops recording data if I stop moving. When I start moving again it wakes up and starts recording. Some data is lost while it realizes data is coming in again.

Aside: I turn autostart OFF. Zeros are data too, so I say record 'em.

Maybe set it for Always On or Clock Time or whatever the mode is named that counts zero speed time as data, then hit the lap button when the countdown starts at 5, lap button at the turn (if you can, or close to the turn), then lap button at the finish line. That should get you pretty close after subtracting out those 5 countdown seconds.

[Jetmugg]

Good ideas all around.  I need to dig a little deeper into the Joule options.  When I download the data after the ride, finding the turnaround is easy (I stop pedaling momentarily).  It's the accuracy of the start, and having the "Ride Time" start at zero that seem to be posing the challenge.  I'll see what the various Joule options are before trying again next week.  Keeping an eye on the time and distance seems to help keep me pushing during the event.  I have to resist the urge to try too many mental calculations while riding, however.  I should just be thinking "pedal harder, pedal harder, pedal harder".

I haven't gotten any more corrections since early yesterday and I'm leaving for Hermann in a little while so I moved up the timetable on the USACycling upload.

Hey Mark,

Sorry to bother you, but I emailed USAcycling about my license because it still says I don't have one.  Did you by chance send in my form and check?  Kristen said she would put me under The Hub when she receives it.

Thanks so much!!

No trouble at all. I have a message off to USACycling to find out what's up with it.

Thank You

I just heard back from USACycling. They have the paperwork and have assigned you a license number (378398). You even have results posted

You should be getting your license in the mail uhhhhh... soon

...then hit the lap button when the countdown starts at 5...

This is the quirk in the Joule software.  The Joule will fragment files any time the bike stops for a minute or so (stopping at red lights for my commute to work can often divide the overall data file into several fragment files).  When I try to start an interval when the bike is not moving, and then choose "merge" for all the file fragments during download, the start of this lap - and thus my start time - is lost.  The data is collected but the start interval is not stored.  However, if I download the TT fragment separately rather than merge all the fragments, I do get an accurate start and a finish that is accurate within the amount of time it takes me to get off the aero bars, get my fingers on the lap buttons to push them...The downside to that is I end up with separate data files for my warm up and my TT (I would prefer to have them all together in one file and be able to view the TT as a lap in the file).
