I work from home, so I cycle to work specifically to get more kilometers under my tires.
Distance: 9 km each way, so 18 km per day (Greater Kailash One to Moti Bagh / Satyaniketan)
City: New Delhi - how sad, it looks like I'm the only Delhi-ite in this thread
Bike: Trek 3700 mtb, soon to be changed to a Trek 1.5 roadie in under a month.
Number of days a month: Increasing every day. Last month it was about 5 days, this month hopefully it will be 10 to 15 days.
Major Junctions: AIIMS would be the biggest one, but I pass through a bunch of flyover intersections all the way to work.
Major climbs: Most of Delhi is flat as a pancake. The AIIMS flyover might count as a climb, but not to most of the hardcore nutters in here

Future plans: Once I get a new MacBook to work with, I plan to cycle almost every day. Of course in my case it's purely voluntary since most of my office works from home, but I plan to do it as a sort of minor training.
I have it good; my boss is very supportive of it and is working to making our office more 'green' with initiatives etc. But cycling to work is pretty much unheard of in Delhi it seems, aside from the usual security guards etc. With Delhi's traffic and pollution I'm hoping the govt here encourages businesses and corporations to allow / welcome / encourage cycling to work but who knows :/
