It’s April and iRunFar’s on its way to California. This means one thing: it’s Lake Sonoma 50 Mile time! An unrelentingly hilly but beautiful course with a sporty 10,500 feet of elevation gain, the likes of Tropical John (Medinger) as your fearless RD and hospitality guide, and not one but two solid post-race parties. It’s not a wonder at all why Lake Sonoma has become one of North America’s most competitive ultras.

Additionally, the Lake Sonoma 50 Mile is the last race in the Western States 100 Golden Ticket race series, and this means that the top-two men and women earn entry into Western States.

This year at Sonoma, we’ll see another strong field of men prepared to make the 50-mile, out-and-back, almost-never-flat voyage around the race’s namesake lake.

As you’d expect, we’ll be providing pre- and post-race interviews as well as live coverage on race day.

Many thanks to Nathan for their generous support of our coverage of this year’s Lake Sonoma 50 Mile.

Thanks also to Julbo for making our coverage of Lake Sonoma possible.

Be sure to check out our women’s preview, as well!

Winner Potential

Alex Varner is the defending Lake Sonoma champ (interview). Last year he was untouchable by the rest of the field as he set a new course record by about a minute and a half and finished ahead of everyone else by about 14 minutes. His 2015 trail season was also highlighted by a new course record at the Quad Dipsea last fall. Over the winter, he’s been plagued by a nagging hip injury that’s limited his training. In the midst of this, he squeaked out a fifth place in a competitive 2016 Way Too Cool 50k field. He said on social media last week that he’s going to give Lake Sonoma his best shot anyway.

2015 was quite a year for Dylan Bowman (pre-race interview), wherein he cemented himself as a major player in the international trail and ultra scene. Among his year he collected victories at the Tarawera Ultra (interview) and Ultra-Trail Australia (interview) as well as taking a highly esteemed second at The North Face Endurance Challenge 50-Mile Championships (interview). A month ago, he rocked the Way Too Cool 50k, taking third. He’s been traveling in South America and arrives home a couple days before race day. I say he could go all the way so long as he has no travel-recovery issues.

Little by little, the previously-short-distance trail specialist Mario Mendoza keeps squeaking up in distance, running longer and longer trail races. Last summer and fall, he took fourth at the USATF 50k Trail National Championships, second at the UROC 100k, and won the Moab Trail Marathon. A couple weeks ago, he took second at the Chuckanut 50k. So, he’s already run a longer ultra and held things together for nine hours. Lake Sonoma’s six hours should be a piece of cake! Hah! ;) Longer-distance experience plus his kind of talent, no doubt he’s going to go for it.

Contenders for the Top Five

Jim Walmsley already has a Western States Golden Ticket, which he earned by winning the Bandera 100k in January, so it looks like the guy just can’t stay away from this weekend’s competition. Last year Jim took fifth in 6:41 here, in what was his second 50 miler. Since then and in addition to Bandera, he won the 2015 JFK 50 Mile, his second win there, and the 2016 Moab Red Hot 55k. I suspect he’ll be in the mix all day.

I think Matt Flaherty has enormous talent on a course and at a distance like Sonoma, and our sport has missed him while he’s been suffering a foot injury and making the journey back to fitness. Last summer, we saw him race to seventh place at the UltraVasan 90k while he was on the upswing of fitness. A few weekends back, he took third at the Chuckanut 50k, about three minutes behind second place Mario Mendoza. Dude’s got wheels, and he’ll enter this weekend as a bit of a dark horse as he’s been off the radar for the last bit.

While Zach Bitter (pre-race interview) may have earned himself the reputation of being the guy who runs unending fast laps around a track, the guy’s got much more range than that. That said, last fall and winter, he popped off a 5:17 for 50 miles at the USATF 50-Mile Road National Championships and then an American Record for 100 miles on the track (report). And now that he’s moved from Wisconsin to the California’s Central Valley, he’s got the Sierra Nevada foothills and the hilly terrain of the San Francisco Bay Area not too distant for weekend training. Thus, he’s probably well on his way to extending his range into hillier and hillier terrain, too. As a fan of the sport, it’s always a pleasure to watch someone with Zach’s kind of talent diversify.

What’s happening with the development of high-end trail running in the San Francisco Bay Area right now is really cool. Great passels of talented men and women gather together to train together (or together via the numbers kept on Strava), and floating to the tops of these groups are some individuals who have the talent and drive to make impacts on our sport. That also said, there seems to be some unbridled and unsustainable training and racing also happening. Chris Vizcaino, who hails from the east side of the Bay Area, is emerging as one of those talents. It was cool to watch him run to 11th place at the 2015 TNF EC 50-Mile Champs, one of the highest-placing what I’d call wildcard entries of that weekend. A month ago, Chris took 13th at the Way Too Cool 50k, what is clearly not his potential. Chris has raced an ultra something like 10 times in the last 14 months, so time will tell if he is interested a long-lasting, high-level relationship with trail running. [Update April 5: Chris Vizcaino isn’t racing.]



At about 15 months into his ultra career, Dan Metzger (pre-race interview) has already run at least seven of them, including three 50 milers or 100ks. That’s a lot of tough racing miles. Of note in his short career so far is a sixth place at last summer’s USATF 50k Trail National Championships a couple minutes back of fourth place Mario Mendoza and 16th at the 2015 TNF EC 50-Mile Champs. Daniel’s just 21 years old, which means he definitely has some still-developing and probably a whole bunch of already-developed-but-unharnessed potential. From a fan’s standpoint, I hope he finds a sustainable relationship with our sport, because I think he could make a big impact in it.
