I've been ramping up my training sessions (cycling) for the last few weeks to get in shape for a commitment I made. Getting ready for an ultra-endurance event in 2 years.
I train about 4-5 times a week, during weekdays I tend to focus on recovery rides, interval training and build up my general endurance. During the weekend I ride about 80-130 miles, two days in a row. (If possible) These long rides are to build my mental game, to get used to being in the saddle for long stretches of time and to learn to keep going while being tired.
So far this is doing wonders for my condition, pacing and mental endurance. But one thing I am worried about is getting enough sleep. Naturally, I sleep about 5 - 6 hours a day, I wake up without an alarm. Waking up feeling rested. Since I started training more frequent I see my sleep drop to 4 - 5 hours while not waking up tired. This is extremely short, even for me.
From what I've been told. Sleep is essential for focus, productivity, muscular and skeletal system recovery, memory, energy levels, mood and a lot of others. Although I feel great a.t.m. Should sleeping this little be worrying? What would be causing this drop in sleep?
