Calibrate, calibrate, calibrate.
After gearing up with my iPod Nano, my Nike+ AirMax Moto Shoes, and my Nike+iPod connection kit, I learned that, without calibration, the Nike+ system makes me look SLLLOW.
For those of you who don’t know, the Nike+iPod system is a combination of sneakers, ipod, a transmitter and a receiver, which collects running data from your sneakers (via the transmitter that slots into the specially designed shoe), sends it to your iPod (via the receiver that clips into the dock connector), and syncs it to nikeplus.com to track your runs. During a run, you can have the Nano give you feedback via headphones about distance, etc.
Sounds great, right? Is it, sort of.
Unless you calibrate the sensor on a track, by running a set distance and telling the sensor what that distance was (400 meters, a mile, etc), the sensor can be WAY off, which is disconcerting during a run.
During the 4-mile Run for Central Park, I would pass a mile marker, and a long time later, the Nano would say I just went that mile. When I finished the race, the Nano thought I had gone 3.49 miles. That’s a huge difference between reality.
The drag is that it synced that race to the site… so it thinks I ran MUCH slower than I did, because the clock was accurate, but the distance wasn’t. Bummer.
Anyway: I’m going to calibrate the sensor this weekend, and I’ll report back then.
Love to all. Even you, the guy driving the limo, fast and in reverse, through the train station parking lot.
