There's a guided ride tomorrow, at Alafia. The park opens at 8am, you might want to get there then and get yourself and your bike situated, the guided ride starts at 9am
. The blue trails can be technical, green are beginner, diamonds are for those with good insurance plans...
Join the group ride and you'll get to see the good blue trails and don't worry about getting too lost, the loops are fairly short, about two miles or so each, one way, and well marked.
There will be a bunch of people out there, so just strike up a convo and you'll meet some great riding companions.
See you out there!
