This is a very popular, fast 300k brevet. We start by heading through Corona to the Santa Ana River Trail and following it all the way to Huntington Beach and the first control. There we head north either on the beach path or PCH (your choice) and then inland on the San Gabriel trail to Las Lomas. This is a 45 mile stretch so stock up on calories. The climb over the Santa Fe dam is scenic if you look to the mountains. Most riders will get to the Las Lomas control too early for pizza so you’ll have to forage at the 7-11.

Now we back-track for a while until we hop over to the Rio Hondo bike path. There’s a quarter mile stretch of dirt that’s normally rideable, but you can walk it without losing much time. Next we’re on the Los Angeles River trail dealing with headwind for ten miles or so. As we enter the Long Beach marina there are many routes through the area – the important thing is the keep the water somewhere on your right. You can get a receipt in Shoreline Village if you want but if you continue to Belmont pier you will have more options. Both areas are acceptable for receipts. If you missed out on pizza I can recommend Chronic Tacos.

Now we follow the beach path a little longer and some quiet(ish) roads until PCH which we follow to Newport Beach. Now we ride more bike paths to one of my favorite controls at Crossroads shopping center in Lake Forest. It’s hard to beat sitting by the illuminated fountain as the light fades while eating Pad Thai. The last section is a mixture of bike paths and quiet roads but contains some climbs – noticeably Pioneer Way and Green River Road. Some riders may find the gate from Lakeview Ave onto the Santa Ana trail locked when they get there. In this case, continue on Lakeview and make the first right onto La Palma. You will rejoin the route 4.5 miles later. This is explained on the cue sheet.

Total distance is 188 miles with 4000′ of climbing. Because it is so flat, has few stop lights or stop signs, and only has four intermediate controls, many riders have completed this route in under 12 hours. Most riders set a personal best on this route. It is ideal for randonneurs attempting their first 300k and for experienced riders looking for an easy 300k for PBP qualification. You will want to ride a more difficult 400 and 600 km route – we have several on the calendar.

If you have not registered by the morning of the ride, please be sure to get your registration complete at 5:30. It takes several minutes to register and there may be a line. We will be starting in the Goodfella’s parking lot. You will need to visit me in my hotel room when you finish. There is a small amount of public parking available outside the Best Western.
