I love my iPhone!

Yes, I have posted this in the right spot!!

We've been thinking of a way to get me to ride faster on my bucket. The bucket is quite capable and so am I aparantly, but for some reason I end up just pootling along like I'm on a Sunday ride. I know a lot of that has to do with this being only my second year of racing and I'm still a little stuck on road riding (which I've almost given up because I find the bucket so much more fun... and safer!) and that I'm not really very aggresive and don't like being pushed off the track. However I find if I'm on my own or if the rest of the field is a long way ahead of me (which they often are) and I have no one to chase I get even slower and lose focus.

So we downloaded a lap timer for $16 onto my iPhone which works off GPS coordinates and times your laps for you.
Taped the phone to my bike this morning and went for a ride around Kaitoke track to see how it worked. It was wicked!!

It keeps a record of your lap times, gives you your last lap and predicts your next lap for you (that's pretty funny!). You can program in different tracks and it also gives you a picture of the track and the lines you took! Very cool!!
So I'm hoping that this will give me some motivation to ride faster by trying to beat my last lap time and get new PBs. Still have a few things to play with and a few little personal error glitches to iron out, but on the whole I'm very pleased with it. Bring on some PBs and hopefully me going a bit faster than a snail!

Just downloaded a similar program from racechrono for my nokia that does the same thing you described, absolutely amazing little program with incredible detail, allowing sector times as well. Using the gyro it measures g forces in all directions so you can measure braking forces etc, the iphone should do the same.

Yeah it does, not that I rack up much g force on my bucket, but yep braking and acceleration forces and lean angle degrees, average speed etc. It's cool eh, and a crap load cheaper than a proper lap timer if you already own the phone!

Have to have a look for that one. (I like the fart simulator, hours of mindless entertainment playing Simon Says fart styles

)

What's the name of the app Trudes? might get that app too, sounds impressive.

I've been thinking about this. I'm surprised that the sampling interval on a GPS would be accurate enough to accurately time a lap.

If you crossed the finish line doing about 100Km/h and the GPS had an error of 3m, then that would be an error of about 1/10 of a second. And if it only took GPS samples every 200ms, then that would be another 2/10 of a second.

I guess that is fine if your consistency is such that you lap time varies quite a bit from lap to lap.

What does the application say its accuracy is on an iPhone?
