The Mendocino Coast 600km is not the most frequently run SFR event and it isn't the one with the most participants in a given year, but as there is a notion of progressively longer events within our 'PBP Qualifiers', the Mendocino Coast 600km has some luster as a 'signature' brevet.
The
route from SF to Fort Bragg and back is attributed to Daryl Skrabak though it is listed on the RUSA site as submitted by Todd Teachout who was the SFR RBA when route numbers were first assigned to existing and new routes. According to RUSA records, this route was first run in 1999 with Daryl Skrabak as RBA. Much like PBP itself, though not for the same reasons, the Mendocino Coast 600km was not run every year. Daryl ran the brevet once in 1999, and after that it was next run in 2004 under 2nd year RBA Todd Teachout. Todd listed the event again in 2005 through 2007. After a gap year in 2008, the event was again run, this time by 2nd year RBA Rob Hawks with subsequent versions run from 2010 through 2018 (which was the longest consecutive string of years for the event).
The Mendocino Coast 600k has been run as early in the year as April 10th (1999) and as late as August 27th (2022). Since 2009 it has always been held in May, with some years including a repeat later in the summer.
The start time varied in the early years, with a dual start time in 1999 of midnight or 04:00 depending on the speed of the rider. Though the start time in 2004 is unknown, as of 2005 the start time settled in as a morning start, varying between 07:00 and 09:00 until 2009 when it was changed to 06:00. In 2012, to avoid conflict with the Amgen Tour of California the start time was 05:00. In 2013 the event returned to the 06:00 start time where it has remained.
From the first running of this RUSA brevet route in 1999 through 2019 the route was known as the Fort Bragg 600km. Since 2021, the route name has been the Mendocino Coast 600km.
The route has been changed little since 1999, but thankfully, many of the miles of highway have been repaved in those years including long portions of CA 128, including the famous
Tree Tunnel section. Two changes to note are that until 2015 the start and finish both were at the Golden Gate Bridge visitor plaza at the south end of the bridge. In 2015 the finish was moved to East Beach at Crissy Field which allowed for a much nicer reception for the riders and much calmer place for those waiting to greet the riders. In 2016 following a widening and repaving of Sir Francis Drake Blvd, the return from Point Reyes Station to San Geronimo changed from a route through Nicasio to a route through Olema and over the Bolinas Ridge via Sir Francis Drake Blvd. This actually shortened the route enough so that the start was also moved to East Beach at Crissy Field. Because of curfew hours at East Beach, the start reverted back to the Golden Gate Bridge visitor's center plaza and to off set that, the turnaround point in Fort Bragg was moved a short distance further north.
The route is rumored to be the most difficult (paved) 600km route among the four Northern California brevet clubs (Santa Rosa, Santa Cruz, Davis and San Francisco), but that perception may not be backed up by metrics. Ridewithgps lists the total climbing at 19,353' (the CA: Davis 600 known as Davis-Quincy-Davis has > 20,000' of climbing). This reputation seems to hold true if one looks at finish times as they are generally longer than those on other local 600km routes, but the elevation gain on the Mendocino Coast route may not be as much as Ridewithgps advertises as many riders record between 17,000 and 18,000 by the finish of the route.
In the early years, there were no staffed controls on the course. Since 2007 there has been a staffed water stop. In 2007 this was so unofficial that it was not listed on the route sheet and was only organized the morning of the start. Since 2009 a staffed water stop has been an official feature of the brevet though it is not a timed stop. Until 2013, that stop was at Paul Dimmick Campground, less than 7 miles from the coast. Since then the official water stop was 15.5 miles further east, near Philo, CA at the Indian Creek campground. Now, the term 'water stop' pretty much undersells the true nature of that course feature. When first set up in 2007, it was not much more than a water stop, having been devised and deployed on the fly the morning of the event. Two volunteers pretty much asked the riders what their favorite ride food was and made a list of the answers, did their best while shopping at the Healdsburg Safeway and then drove up to Paul Dimmick campground. In 2009, that water stop was formalized as noted above and began to offer both hot food, and tents and sleeping bags for those riders wanting to punctuate their ride with some sleep. Even though the location did move, the 'water stop' is as deluxe as a campground can be with a wide menu of hot food and drink, a campfire and multiple tents for sleeping. In 2016, the radio podcast Nocturne recorded a two part episode that does a
deep dive into randonneuring in episode 23, and then in episode 24 visits the Indian Creek campsite and features how the
randonneuring community works together to see riders finish.
Weather is always an issue on this ride if for no other reason than that the riders are out for roughly 25 to 40 hours. Day time vs. Night time temps always range widely even on good weather days. Weather was likely most a factor on the 2007 version when it began raining on the riders around the 50 mile mark in Petaluma and it continued for perhaps 20 more hours. From 2009 through 2023, the May version of the event has generally been favored by 'good' weather (no rain, moderate winds) but even then the temperatures ranged from ~100F to 45F on the same day. This can happen quite quickly too. In 2012 in the span of less than 35 miles (from the Yorkville Highlands to the junction of CA 128 and CA 1) the temps ran that complete range as riders left temps of 99F at the Sonoma/Mendocino County line and 49F when they reached the coast in wind blown fog as the sun set. Wind is often present at some point on the route and most typically so on the stretch between Healdsburg and Cloverdale where riders get 'relief' from the wind by climbing up to the Yorkville Highlands. Headwinds return for the crossing of the Anderson Valley and then riders once more get a break, this time from the Tree Tunnel. Once clear of the Tree Tunnel headwinds return once more where the route meets the coast at the mouth of the Navarro River and slow the riders on the run up to Fort Bragg at the nornern terminus of the route.
In 2018, the date for the event was pushed later in May hoping for a little better overnight temps and possibly less wind. That effort was a failure. While the very early morning temperatures were not any lower than in any previous year, they were low for a much longer period of time. Similarly, the wind was no stronger than any other year, but it was strong for much longer.
There have been 606 participants on the event through 2024. In 2018 when this history was last published there was been a bit of a shake up on the list of most frequent participants. Bob Buntrock broke the tie with Richard McCaw as the riders with the most completions, but Bob had to miss the event in 2018 owing to a broken hand and everyone moved a little closer to him on the list. Since 2018 the list of most finishes has undergone a fair bit of rearrangement Here are the most frequent riders of the MC 600km:

The Mendocino Coast 600km brevet has been ridden by a wide range of randonneurs. Of the 606 finishers, 73 have been women (12%). The youngest rider to finish was 18 years old and if recalled correctly that rider had celebrated that milestone event in the weeks just before participating. No data is available for oldest rider but I know several that were in their 60s at the time of finishing.
Max Poletto, Bill Brier and Carl Anderson had heldthe shortest elapsed time at 23 hours and 33 minutes until 2019. Since then the shortest time has changed twice, first to 22:50 (Erik Nohlin and Chris Burkhardt), and then in 2022 when Yuri Gonzag lowered it to 21:04. These, plus Zach Morvant's 2023 time are the only finish times under 24 hours, and there are only 5 other finishes under 25 hours (three of those occuring in 2018) and a grand total of 13 finish times under 27 hours. Tom Haggerty holds the current longest elapsed time and he is unlikely to ever relinquish that title. There is a story behind this time and Tom's record is 40:00.
Geoff Hastings and Peter Burnett used to hold the record for multiple finish times with the largest difference in time. Both have their shortest and longest times over 9 hours apart and that spread is still noteworthy, however Tom Haggerty now holds the record of widest margin between shortest and longest finish times: 28:53 done in 2014 and the above mentioned 40:00 from 2007. Michael Bloomfield is perhaps the most consistent finisher. All three of his finish times are within 7 minutes of any other of his finish times.
Here is a chart showing the break down of finish time ranges for all 606 participants:
