Just leave it in your pocket our your backpack. It'll still pick up the GPS signals.
One drawback of leaving it in the pocket is that the "stop logging" button on the bottom is stupidly easy to accidentally press. They really should require a 2-second hold down or something to stop the log. I've done a couple rides where I finished, went to stop the log, and discovered it actually stopped logging almost immediately after it went into the pocket/pack.
