This is a two loop race for 50K. The bulldog trail is a 6 mile long uphill. It is specially tough for the 2nd loop.
We were fortunate that day. The temperature was below 80 all day long. However, it was still very exhausted to climb the hill under the sun. I got a chance to use icy water to wash my head in one of the aid stations.
There were many aid stations along the way. The volunteers were very helpful.
The event advertised to have free pictures for all runners. There were photographers along the way. However, there has been no photos to be found for 2025 event for some reason.
Be prepared for hills and heat
Bulldog 50k is two 25k loops with plenty elevation gain and loss. It was very hot, as in recent years (according to other runners). The trail is rocky, and I … MORE
Bulldog 50k is two 25k loops with plenty elevation gain and loss. It was very hot, as in recent years (according to other runners). The trail is rocky, and I saw some runners falling. Good views from the top, but few aid stations. Finisher medal of the 50k not much bigger than a coin.
Up first half and down second half
Course: normal ribbon and arrows but no mile markers. It's almost all uphill the first half and downhill the second half with a bit of single track at the end … MORE
Course: normal ribbon and arrows but no mile markers. It’s almost all uphill the first half and downhill the second half with a bit of single track at the end after 21k. Chapparal and well kept trails
People confused with starting line as there wasn’t one and people didnt know where to line up as there weren’t any visible signs available.
Ran one loop. Two, if you are running the 50k. But tiny medal. A little bigger than a coin, really. But you need to do the 50 for a buckle. I’d see unhappy faces if the 50k got the same medal! Watermelon and some drinks at the end. I’d expect more runners, especially for an anniversary race, if they took care of the runners a little better.
Challenging course, great Race Director.
