Hey everyone, I'm coming back home to Jacksonville for a week (arriving tomorrow) to visit the parents and get the kids some beach time. I'll be staying out at the beach. I've heard that running on the beach can be tough on your legs if you're not used to it - so I plan to try a short run there. But I was also wondering where a decent place to get in a long run (18 miles)? My mom suggested Hanna Park but not sure if the trails are too sandy...any suggestions? I've driven past Guano (sp?) River State park a ton of times but no idea if they have any runnable trails ( couldn't find a map on the net either). Thanks for any advice!
