Do not burn yourself out. I was riding too much when I started out in December. I haven't been able to ride since February because my quads haven't been able to recover yet. I took the end of February, all of March off, and tried riding this past week (a VERY light ride around my neighborhood) and my legs have been killing me all week. So I'm seeing a doctor this week.
Some people on these forums will tell you that you just need to build up that strength but I'd let your legs feel back to normal before riding again. If they are sore, don't ride. Otherwise you will end up with an amazing new bike that you can't ride. I'm so stir crazy right now and you don't want to be in this position. Start off slow.
