I recently took 3 weeks out of training as ive started a new job that was supportive of me joining RM. Ive started getting back into training and I'm struggling, particularly with running. I seem to lose my breathe quicker than usual. 3 weeks ago i was running 1.5 miles in about 10:13 and the return in 11:50 (need to swap it round). I could run 3 miles in about 23 minuets. Now I'm starting to loose my breathe after half a mile, anyone know why this could be? Also i currently work 2 pm - 10 pm soon to be 4 pm - 10 pm. Can anyone suggest a training plan or give me an average of how many hours a day i should train so i can manage my time better. I'm going to be giving myself all morning to train 5 days a week so if anyone has any good training plans that will build my fitness fairly quickly i would appreciate it.
