Yes!! My schedule do call for one every 4th week. And after the previous 3 weeks I really needed one. On schedule was nothing but eight miles easy runs for a grand total of 48 miles. I'm happy to report I stood within guidelines, ok I did 49. something!! my week consisted of a complete rest day Monday 7/23 , Tuesday I did the XC run , followed by Wednesday with speed work!! it was pretty hot Wednesday!! Thursday I took a rest day (two in one week) Friday called for an easy run and Saturday I did the Norwalk 9 miler (very humid and scorching hot) today called for only a 8 mile run but I did 10 instead. Well back to business on Monday!!!
