11-13km, depending on the route I take. The ride in is usually faster, going from suburbia (~4km), onto a main road (~1km), through a mall area (~1-2km), then back roads for the rest of the way until a section of fast road (~1.5km) into town to the office. Terrain is hilly - Halifax is fairly well known for its hills. The real killer is on the way home, a hill that's about 1.5km long and has four steep uphill sections interspersed with flat sections. I think the grades are (guessing) 9%, 8%, 10% and 15% - the last one is the real killer (I'm currently walking that section due to a knee injury). For anyone in Halifax I'm talking about Central Ave; I'd be interested to know if anyone can make Flamingo in one go.

I'm currently taking between 35 and 40 minutes to ride in, and 45 to 50 to ride home.
