Emmy - don't you run with your Garmin? The reports on Garmin Connect will tell you your mileage (kilometerage?) over given time spans - yours will be immense.
Best race this year? Paris, hands down - because of you lot.
Best run? San Francisco. Mrs O hired a bike at the Embarcadero and we ran across the Golden Gate bridge and back. Laughing, stopping to take pictures and admiring views. Round trip was about 15 miles but it didn't feel like it.
