Consider changing to a 2610; they're waterproof enough for a bike, and
you can put big enough CF so you don't have to worry about map
uploads.

If it's routes you're worried about, try a datalogger - those from the
link below will last a very long time.

This table is for the XM2 model (there's the XM4 with twice the
capacity of XM2):

As an example, let's take a popular model, the DGPS-XM2, and do some
calculations.
Assume the Datalogger is in a vehicle.
Assume the vehicle is actually moving for only 8 hours per day.
We'll activate the Speed Check function, so the Datalogger won't waste
memory when the vehicle is stationary.
Date and Time will be stored, as that is the most common setting.
Capacity is 196000 timestamped points.
We won't activate 'Automatic Save', 'cos that would be cheating! Auto
may improve efficiency over 50%.
Below, We'll provide some logging times, with various Timed Save
intervals for DGPS-XM2:
1 second save interval: 6.8 days
2 second save interval: 13.6 days
10 second save interval: 68 days (2.25 months)
1 minute (60s) save interval: 408 days (13.4 months)
2 minute (120s) save interval: 816 days (26.8 months, 2.2 years)
5 minute (300s) save interval: 2041 days (67 months, 5.5 years)
15 minute (900s) save interval: 6125 days (200 months, 16 years)
