I saw something from another thread:
"Basically its easier to Maintain Quality then it is to build it.
So for Schumachers Group if they are at 85%-90% fitness all year. Which if probably the intensity/"Difficulty" they talk about. It doesn't become hard for them to get into whatever "Specific endurance" they need for there given event.
Its the reason someone like Shelby houlihan can drop fast 4:20 something Mile indoors in February and then be prepared to drop a fast 5k in August. She's not peaking twice shes just never that far away from being close to her highest fitness level."
I just know that they run a lot of mileage and do mile repeats during base phase.
Basically I don't know if I should take 2 weeks off after xc season and then have to build all back up. Especially since my season ends mid October and track starts up at the end of February and I'm not that good of a runner I only run 20:xx for a 5k. 6:1x for 1600, 12:3x for 3200, and 2:5x for 800. I only run like 20mpw
