Island Half Marathon
Alameda continues to deal with ongoing construction, but we are hoping by September we will be back to a single loop course. If not, we will still have the beautiful SF skyline, Alameda parks and USS Hornet views along the trail.
The course is fast and fast with some unique access to the old Taxiway and scenic landmarks.
All runner will receive a quality t-shirt, medal and post event food, beer and refreshments
