Ascend Spring Training (Week 15)

Weekly Newsletter

Week 15 – Monday, June 8, 2026

We have arrived at the final week of the Spring 2026 Ascend Trail Running session.

Over the past fifteen weeks, runners have logged countless miles, climbed thousands of feet, tackled challenging workouts, explored new trails, and prepared for goals ranging from first trail races to ultramarathons. More importantly, we have continued building a community that shows up consistently, supports one another, and enjoys the process.

Before looking ahead to race weekend, we want to thank everyone who joined us for Global Running Day last week. We had a fantastic turnout at Sports Basement, met several new runners, and shared the trails with a number of local running groups. It was great to see so many people celebrating the sport together, and we appreciate everyone who came out and represented Ascend.

This Wednesday we return to our normal location for a short threshold session designed to keep the legs moving without adding unnecessary fatigue. Those racing at Cool Moon should feel free to shorten the workout, reduce the number of repetitions, or simply join us for the warm-up and social time.

There will be no official Saturday group run this week as many Ascend runners will be racing, pacing, crewing, volunteering, or spectating at Cool Moon.

Good luck to everyone racing this weekend.

For runners racing Cool Moon, the goal is simply to keep the legs moving and maintain rhythm without creating additional fatigue. Feel free to reduce the number of repetitions, shorten the workout, or run entirely by feel.

At this point, there is no fitness left to gain before race day. Focus on arriving at the starting line healthy, rested, and ready to run.

For everyone else, this is an opportunity to get in one final quality session before we officially wrap up the spring training cycle.

Course Notes

Cool Moon remains one of the most unique and challenging trail races in Northern California. While the event has a welcoming grassroots atmosphere and generous cutoffs, the course itself should not be underestimated.

The race is built around two primary loops:

Trail Map (Strava link)	Length (miles)	Elevation Gain
Cool Moon North Loop	~ 13.5 miles	~2500 feet
Cool Moon South Loop	~ 11.5 miles	~1000 feet

The North Loop is approximately 13.5 miles with roughly 2,500 feet of climbing. This is the more difficult of the two loops and includes both Pig Farm Trail and Salt Creek.

Pig Farm is steep, technical, and rugged, but benefits from at least some shade. When you finish Pig Farm, you get the last third of the K2/Training Hills climb, which is notoriously difficult. Fortunately, The Ranch aid station appears shortly after the climb and offers a chance to regroup before heading deeper into the course.

Salt Creek is often where runners begin to feel the effects of the day. The descent is rocky and technical, while the climb back out consists of a long series of exposed switchbacks that can become extremely hot during the afternoon. Runners that don’t manage their core body temperature and hydration will struggle here.

The South Loop is approximately 11.5 miles with about half the climbing of the North Loop, but much of the terrain remains exposed. The signature climb is Knickerbocker, which is steep and technical, but thankfully not too long. You encounter that immediately as you cross a creek.

Course Navigation

One of the biggest challenges at Cool Moon has nothing to do with fitness. Every year runners miss turns on this course.

The course is typically marked very well, but there are multiple trail intersections where the North and South loops share sections of trail. Every year runners miss turns, follow the correct trail in the wrong direction, or accidentally continue onto the wrong loop.

Do not rely exclusively on your GPS watch for navigation. Because portions of the course overlap, watches can occasionally become confused about which loop you are on. Trust the course markings first.

Aid Stations

North Loop
The Ranch (mile 4.5)
Top of Dam Switchbacks (mile 8.8, water only)
Knickerbocker (mile 10)
The Ranch (mile 12.3)
Cool (mile 13.5)

South Loop
Knickerbocker (mile 16)
Pilot Hill (mile 19, water only)
Catecroft (mile 20.5)
Knickerbocker (mile 23)
Cool (mile 25)

Aid stations are frequent and well stocked. Take advantage of them.

Current forecasts suggest temperatures could be warm this weekend. Fill your bottles at every aid station, stay ahead of hydration, and do not wait until you feel thirsty to start drinking. Make sure you are also replacing electrolytes throughout the day, especially if temperatures climb into the upper 80s or beyond.

Cool Moon rewards patience, good decision-making, and steady effort. Manage the heat, stay on top of fueling and hydration, pay attention to course markings, and enjoy one of the toughest and most rewarding race weekends of the year.

Volunteers Still Needed

Cool Moon is still looking for volunteers throughout race weekend.

If you have friends, family members, or fellow runners who plan to be in the area and are looking for a way to be involved, volunteering is a great option. Aid stations, course support, and finish-line duties are all critical to making an event like this happen. If you know someone who might be interested, please encourage them to reach out to the race organization.

Race Director Spotlight: Martin Sengo

If you are attending Cool Moon this weekend, take a moment to thank Race Director Martin Sengo.

Martin has been a fixture in the Auburn trail running community for years and is one of the primary reasons events like Cool Moon continue to thrive. Directing a race of this size and complexity requires an enormous amount of work, and Martin has built a reputation for doing it with professionalism, energy, and an amazingly positive attitude.

Outside of race directing, Martin is an accomplished ultrarunner in his own right. He is a multiple-time Badwater 135 finisher and has completed events such as Cocodona 250, Moab 240, Arizona Monster 300, and countless other races ranging from local trail events to some of the most demanding endurance races in the country. In a few weeks, Martin will also be running Western States.

What stands out most, however, is his willingness to share what he has learned. Whether answering questions from first-time ultrarunners, helping athletes prepare for difficult races, or simply encouraging people along the trail, Martin has spent years giving back to the community that surrounds these events.

If you have the opportunity this weekend, introduce yourself and say thank you.
