My main event this year is 24h race scheduled in the late August. It's my first race of this kind, I'm aiming on at least 200 km. Obviously anything above 200 km is a bonus considering lack of experience (220 is a wet dream).
I have 7 months ahead of me, and I'm really looking forward to it. My training is going pretty well right now, weekly mileage is about 112 km (70 miles) for the last couple of months. I'm still running only once a day, winter and snow/ice on the surface make my runs slow and careful.
In order to achieve my goal, should I later include double days? Is 100 miles/w enough to knock on 200 km in 24h race? And what is my main obligation -- be consistent with my running is kinda obvious, should I extend my long runs to 6-8 h and run really easy, are tempo runs and longer intervals more important?
Thanks in advance!
