How about a conservative approach by taking one step up on the Jack Daniels VDOT from a 58 to a 59? This requires a 17:17 5k at a 5:33/mile pace. For the 3.75 - miler on the Fourth a finish time of 20:51 is needed.
While Sundays slow long run was eminent it shall not be the imminent pace on the Fourth of July!
