DH wants to keep track of how many miles we've gone specifically with the stroller. My dad and stepmom had one, but they can't remember what brand they had or where they got it REI suggested a wireless bike odometer, but we don't know where to go from there.

I bought one of these at REI years ago but didn't really use it. It's not super accurate so I use my Garmin GPS instead for exact mileage/pace.
