How To Get Rid Of Sore Muscles?

Yesterday I was invited on a "daycation" with one of my friends. We went to a park for about 2 hours and ran around the whole time. Then walked around town for about 3 hours, and went to a water park for about 5. To say the least, I am very sore now and didn't sleep at all last night. So, what can I do to get rid of this? I took some ibuprofen about 3 hours ago and have been staying hydrated but it isn't helping at all. How to I get rid of the soreness? Thanks.
