as to the sleep, I've been getting less sleep the past week and didn't hydrate like I should after rides, add that to my allergies and I've been feeling exhausted and having shortness of breath, I slept in extra long today (11am) since I didn't finally fall asleep until midnight...I had some serious sleep to make up, and now I'm guzzling water. I truly feel and ride better when I treat myself better. I had one night out drinking and got wasted and it really took its toll long term in the week. I rode hard yesterday and noticed my heart rate was really high throughout the ride which caused me to tire out faster. I think its really important to pay attention to the little things you change. Sleep deprivation and lack of hydration as well as not eating the right foods for going hard will make a huge difference in performance from one day to the next.
