Rest, feet up, decent meal(s), early to bed.
I usually do pretty much the exact distances you suggest at the weekend. The 30-35 miles on Saurday morning is usually a pretty low intensity. The Sunday morning ride is eyeballs out for 2-3 hours. I just follow the above. Monday I'll do a very gentle commute before a really hard 40 mile training session on TUesday night.
To be honest, once the body gets used to the regime you'll find it becomes much easier. Sometimes I amaze myself with how fresh I feel after a really hard ride, other times I come in feeling crippled. Alot can depend on what else has gone on in the day. I find stressful periods at work seriously affect my ability to ride well and recover. DIet and sleep obviously help.
