There is really nothing magic, but there are things that you can do to help your body to recover faster.
First, stretch again tonight, but make sure your legs are warm when you do- don't stretch a cold muscle. Massage your legs: from your feet -up your calves and hamstrings to quads ---well if you can, and raise them above your heart. Kick back and watch TV or do your homework with your legs up. If you have any specific locations that you can ice for 15-20 min, that helps immensely. That's why pro football players take ice baths -- good for preventing inflamation.
Also, make sure that you are drinking plenty of water all day and eating well all day- every day. Try to eat/drink something healthy with carbos and some protein within 20 min after a workout. Take vitamins: especially a multi vit, and lots of Vit C.
If you have any problems or questions, tell your coach. He or she should be training you well and not breaking you down. You don't want to get injured because you are doing too much too fast.
Tomorrow morning walk and stretch again, and if you have time massage and ice. Some people take an anti-inflamitories (like Motrin) but only under your parents and coaches supervision.
