Training suggestions

I have a current training plan which is based around me being able to ride Monday - Friday. I work evenings and weekends,have a few hours during weekdays to ride, as well as a whole day on Monday and Friday. I'm doing around 10hrs a week so far and it feels manageable.

Monday - Z2 - 2hrs Tuesday - Group ride (Chaingangs, threshold) 1hr workout, 2hrs endurance at the end Wednesday - Recovery ride/day off if I'm tired Thursday - Group hill ride - 1.5hrs Friday - 4hr ride

Sometimes on Monday I fancy going harder as it's a free day for me after working the weekend, but I don't want to neglect Z2.

Would this be fine? Is it just down to how I feel? Any changes I could make?

Tuesday and Thursday rides are quite set in stone as they're group sessions, but have freedom to move the others around a bit.

Cheers
