Bad trainning Long Endurance

Training today was bad.  Did a Long speed endurance 80/120/80/120/80m off 6’. I was tired from work yesterday where I had to do manual lifting and boxes in the shape of chairs. It made it difficult to figure out how to carry them as each on was arranged and stacked differently. The day before I did an Anaerobic tolerance sessions LS: 2/3 x 2 x 200m off 1’/12 and a late night doing life drawing for animators so didn't have time to recover. It's a difficult balance to well, You have to work to earn money and pay the bills but you also have to train for the Olympics. My body can't do them on consecutive days, it has to be one or the other. I must find another job that will allow me to do that. It's a never-ending slog and sometimes I wonder if there is light at the end of the tunnel.
