A bit of description of your route profile.
Mostly flat but has hills at either end. Roads, bike paths, footbridge, (bikes allowed), track next to the sea, track next to graveyard. 5 days a week all, and I mean all weather. At all times day and night, (I work shifts).
What kind of bike you ride. (photos would be cool) Camera batteries not charged, but a Salsa La Cruz 2008. (not as pretty since the Stem recall

) Giant ATX 860 2002ish, (currently being transformed into a winter/shopping commuter). Trek 8500 MTB 2005.
How you carry your gear and what or how much (volume) stuff you bring on the ride. Hiking back pack, includes work clothes and ride home clothes, lunch, survival kit, (earthquake country), toolkit, sunblock, little bottle of Pedro's chain lube. Spare food, inner tubes for road bike and MTB. Rain cape, phone, lights, shades/clear shades, bungy cords, gaffa tape, shower gel etc.
Distance & time (average speed if you care to share) 16.5km depending on route one way. You can give or take a km, throw in another hill etc. Takes 45-55mins. If windy, (it's always windy to some extent), over an hour as parts quite exposed. Average 17km-22km.
How long you've been doing this and any thoughts you have toward the future of your commuting. Couple of years, no plans to change, would like to include a Surly Long Haul Trucker at some point to the stable.
