Kilometre nibbler
Well, I'm not a commuter at the moment (I doff my cap to you).I'd love to be able to find hills close enough to me to allow me to do that. I've got to ride about 20miles before the terrain starts going upwards noticeably. My daily commute is 20km each way with about 60m of climbing.
As a dilettante weekends-only rider I can pick and choose my routes, carefully threading them through all the hilly bits.
