mid summer training

This is the time of year when training becomes more difficult: my enthusiasm wears off and i I start to get a bit tired from a lot of races. Last weekend, I did another duathlon and had a pretty good result (3rd). i was a bit disappointed with my run; running 46 minutes and something. i have been working at my running and have gottena bit faster but it is still a challenge. Otherwise, my training is going well. This past week i cycled for 4 hours on monday; swam on tuesday; ran twice on wednesday (7 k and 9 k) swam thursday and friday; cycled on thursday for an hour and a half; ran friday a speed workout and cycled for 3.5 hours saturday. That is about 18 hours which is a lot. My coach calls it "maintaining your aerobic base" which i think i used to fail to do. i would do lots of short races in previous summers but no long rides or runs. You do loose your base endurance when you do this. Tomorrow, I am going to go for a long run.
