Am i overtraining?

Im an expierienced runner but I increase my training now to 1 hour of biking at 5 a.m. and then a run...Then I have cross country practice and then after dinner I bike for an 1 hour or two. Is this to much? Will I burn out before the end of the season?...

And when I take a day off will it injure me because my body is so used to the schedule?

Maybe instead of biking for two hours after dinner, just bike for one hour, or run for half an hour and bike for one hour.
I think you should only have that schedule 6 days a week. Or on the seventh day, take it a bit easy and don't do the after dinner bike/run.
Your schedule sounds really good though. If you are burnt out, then take a small break.
Peace

u should be taking rest days in your programme to allow your muscles to rest and repair. you wont get any injuries from resting buddy!!
