Exercise and anemia

mlb929

I meet with my arnp on my blood work as soon as she can get me in. It may be 3 weeks. I have blood anemia something to do with the red blood cels. My question is I'm starting full marathon training officially on Sunday. I was hopeful to do doubles but not feeling good enough to do all I was doing. I am only running 3x per week and biking 2x with an extra workout or two as I feel well enough to do it. I'm just curious to know if it takes me 3 weeks to get in I know it effects my performance but will it effect anything else?
