I had a great season last year and after the Xterra World Champs late October, I took about 6 weeks completely off training, then started training again with a winter base training program until the first week of February. Then I continued with my regular xterra/half iron training program (which averages about 12 ish hours/week). For a few weeks in February and for the past couple of weeks, I have been feeling excessively tired. In February, I took days off as needed, in March I started to feel better but I could still feel that my legs weren't firing up when running and this has been a on going issue.
I raced the Xterra West Cup last weekend (April 25)and had a good swim & bike but absolutely no legs on the run. I've now been back for a week, I had planned a recovery week for last week but was only able to train for a total of about 2 hrs (for the entire week) due to this excessive fatigue, I am repeating the recovery week this week hoping that I will feel better but feeling more tired than I should be considering I took 4 rest days last week and did only 3 very easy workouts.
My question is, should I be concerned and seek some medical advice or should I just take more rest days?
