Probably not something anyway can answer, but I'm going to ask anyway :)
What is a "normal" level of tired that you all deal with on a regular basis. I juggle my half marathon training with crossfit. Generally I run 3-4 days a week, with crossfit 4-5 (some days are double). I love the strength and physical progress I'm seeing.
I'm still making progress on my runs, but I always wonder if I'm not making as much progress here because of the "extra" activities. This morning was a scheduled 3.5 mile run. I felt tired so I took it all at an easy pace and still completed it. I'm still following my training plan. But if I'm supposed to putting more effort/speed into the runs then today I may not have been on my "A" game.
Long winded post, but I hope someone has advice from a similar situation.
I run 5 times a week and cycle to and from work every day, so I guess for me the answer is pretty tired.
I'm not sure you'll get a specific answer on what constitutes as a 'normal' level of tired though - I technically have no rest days if you include the cycle commute, but will take public transport the day after a run if my legs feel heavy and my pace is considerably slower for the same perceived effort/average heart rate.
