Fontana Days Run Half Marathon & 5K

After making their way along South Lytle Creek Road for much of the first half of the race, runners then transition onto Sierra Road for the last seven miles of the race, changing from a steep downhill to a moderate to mostly gradual downhill run for the remainder of the race, all the way to the finish at City Hall at 8353 Sierra Avenue.
The elevation drop that runners will experience during the race is quite a drop — 2,125 feet overall during the race, from start to finish. And the race is indeed fast — the male record finishing time is 59 minutes, 22 seconds, while the female record finisher clocked in at 1 hour, 8 minutes and 38 seconds (both records were set in 1986).
No walking or race walking is permitted during the half marathon race — the 13.1-mile distance is for runners only — though runners who aren’t yet ready for the half marathon are encouraged to enter any of the event’s three other races for adults, or to join with three other runners and participate in the four-person team half marathon relay.
Organizers note that because the shuttle bus ride to the starting line can take as long as 45 minutes, runners are strongly encouraged to be at City Hall and ready to board the bus to the start by 5:00 AM.
