some one mile intervals on the island. calves giving me some grief. not a great performance, I can't seem to consistently maintain or break through six minute pace on these workouts. could be lack of confidence from my calf problems? I would like to do more 400-800 speedwork but am worried about aggravating things on the track. maybe I should just take it easy for 10 days and then do my best at Riverton on fresh legs? 6:19, 5:57, 6:00, 6:09
