Six Mile on Friday

Last night was fun. A litle snow mixed in keeps it interesting for sure.
Tim's home brew light was fantastic, works like a charm! Now he needs to do a helmet mount light...

The motion based info is interesting, it matches my cateye very close for distance, but avg. speed is lower (i think I had 8.6, I already reset it) and the elevation looks suspect. Very cool to see the route on a map. Good stuff.

i guess all of the 20' ascents and descents add up

Yuppers that was a great time!


Yeah when I looked at my first couple rides on the thing I thought the elevation was kinda nutty, but it isn't saying that we climbed a giant mountain and then came back down. Watch the ride on the player and keep an eye on the elevation. It actually is tallying every foot climbed together. You can even check out elevation/distance to see grade data. Data is actually SUPER accurate for our ride - when it says that GPS signal quality is excellent with only two corrections it means the gizmo had like 6-7 satellites tracking and sometimes more. It knew exactly where we were & when. It also stops the speed timers, etc. whenever I get below 2Mph so the avg. speed/ distance etc. should be dead on.

The thing tracks speed so well that if you hold it in one hand, and pass it to the other hand, it knows it moved and shows the .3Mph or so during it. It tracks elevation so accurately that if I hold it at my waist and then move it to eye level it knows.

From what I have read, due to tire flex, inflation, rider weight, obstacles on the trail etc. factored over thousands and thousands of wheel revolutions during a ride miniscule variations in circumference compared to what the cat-eye is looking for add up. The GPS in the garmin is what tracks speed, distance, etc based on where u r on the globe and is supposedly way more accurate. I spose we should ask Tim for his thoughts?

Also, remember that I was last in line riding so my avg. speed is gonna be a bit slower. Approaching corners the first guy brakes at or just before entry, everybody brakes, I am still on the straight but slowed in line waiting to get to the corner. On hills the first guy brakes before the next turn, I brake 5+ rider lengths sooner to not hit the back of the rider ahead of me. That kinda stuff adds up also to knock down avg. speed.

WHat will be neat is that in the future I can pop our ride back into the unit and during our ride it will show a dot for the old ride, and a dot for our current ride and tell us how many minutes, seconds, feet, etc. we are ahead of or behind ourselves racing against last time, if we even care. Can also have 'dot races' on the website to see where we get better/worse in different conditions.

Anyway, I read before I got the thing that it is love/hate because it tells me in great detail exactly how badly I suck, and where......and will show me in the future how much more I suck at particular sections than I used to suck, etc.......

I know that we didnt climb 1400+ feet in six mile run. Take a look at some Freds motion based info, that looks more realistic for alt. gain.

Anyway, none of this stuff really matters, still a great time riding any way you slice it!!

If you rode the whole park 5 times i dont think you would add up to that much elevation. Check your options in motion based. There is one that will self correct the elevation. That may be a problem. Glad you ahd fun!

Did you just recently purchase this "GPS" that you speak of? What did you buy?

Garmin Edge 305 with the heartbeat gizmo. Unless you ride road I would say skip the optional cadence sensor......and for me the heartbeat sensor pretty much steadily tells me I am near death.....but its cool to see the heartrate overlayed with elevation, speed, etc. on the site.

I'll have to check it out. Watching the dots on the map the changes happen where they should, and each hill doesnt seem outrageous.... I wonder if I change this setting if MB will correct the rides there already??

OK now my GPS says I suck worse. Felt like a hero climbing 1000+ feet!!! Actually thought it was possible with all the little hills. Not the first time I have been wrong.....gonna guess it wont be the last!

Found the motionbased 'gravity' setting and checked it off for future + edited our ride from Friday. My legs don't feel any better though. Old link now showd the corrected data. Thanks for the info on how to fix the problem, Fred!
