Large, organized events that involve cycling, running, walking or a combination of all three always seem to benefit some vague charity that looms in the shadows. The 10th annual Katie Ride, however, benefits a charity that deserves to be in the spotlight. David and Susan Caples started the foundation after their 17-year-old daughter died in an automobile accident. Katie had registered to be an organ donor – that’s how she improved and helped save the lives of five people. The ever-growing cycling event hopes to raise awareness and funds for organ donation. 6 a.m. April 12, Atlantic Recreation Center, Amelia Island, $10-$45.
