It seems the "standard" warm-up distance for a race is 2 miles. Does anyone do more than that? The reason I ask is today I did a workout in the Jack Daniels plan that was 1 hour easy, then 6 X 1200m at T pace with 1 min rests. I thought they'd be tired, but my legs felt better during the reps than they have when I would just do a normal workout with 2 mile warm-up. Is this a fluke or do some people benefit from a longer warm-up?
