Track attack!

  So the final run of the week...track day. I simply wanted 90 minutes with some speed work thrown in...the heat and humidity is high but I felt good. After 4.5 miles I was toasted! I'd done several 400's at 10K pace and it had cost me....I finished the 90 minutes but it wasn't pretty! I look forward to next week and the 10% increase in time. I will see mileage total increase, too! Hope all is well with you!
