A.M. Too much snow for tempo work today. 7-8 years ago I would have pushed it through regardless. But I am smarter now, I think. Tempo runs are effective not so much because they give you strength or endurance, but because they teach you to be efficient at race pace in a race-specific environment. A tempo on snow teaches you to be efficient on snow. I usually do not race on snow, and when the unfortunate circumstance of that does comes around I do not care to get an edge in that situation anyway. So running on snow is valuable to me only for general aerobic and strength conditioning, and I decided to use it as just that. Ran total of 18. First 10 in 1:11:33. Then 1 with Jacob in 8:49, 1 with Joseph in 8:26, and 6 with Benjamin in 46:37. Jenny and Julia did 2 in the Jacob/Joseph pair run. Benjamin ended a record mileage week of 36 miles.
