⏵ Course guide · Overnight Sierra road ultra
The Tahoe Midnight Express Ultra 72 starts at 9 PM Saturday and sends you counter-clockwise around Lake Tahoe on 72 miles of paved road and bike path, entirely self-crewed for the first 48 miles. This is a road and night ultra, not a technical trail race, and the challenge is logistics, darkness, and distance rather than footing. I will walk you through the format and course first, then give you a pacing and fueling plan built for a self-supported overnight effort. There are free calculators along the way to dial in your own numbers.
These facts come from the official Lake Tahoe Marathon event page. Start time options and cutoffs can change year to year and vary by predicted finish time, so confirm the current specifics with the race director before you commit.
The course circles Lake Tahoe counter-clockwise from the Golden Nugget Casino Hotel, finishing at Lakeside Beach alongside the Lake Tahoe Marathon and the weekend's other races. The real character of this race is less about the road surface and more about being entirely on your own for the first two-thirds of it.
From the 9 PM start until roughly mile 48, where the route joins the Lake Tahoe Marathon course, there is no race-provided aid. Every runner must arrange their own support vehicle and crew, and support personnel are capped at 3 runners per vehicle. The first few miles through Round Hill and Zephyr Cove have streetlights, but past that you are running open road in the dark with only what your crew brings.
The course runs on the road, using bike paths whenever they are available, including a newer path off the road near the Sand Harbor boat entrance. Several stretches have narrow shoulders, most notably the roughly 40 yard tunnel at Cave Rock and the section between Glenbrook and Spooner Summit. Brief your crew on exactly where these narrow sections are so they can plan safe stopping points rather than pulling over somewhere with no shoulder to spare.
Once the course reaches the Lake Tahoe Marathon route, you gain access to that race's aid stations for the remainder of your 72 miles, and you finish at Lakeside Beach alongside marathoners and other weekend race fields. That shift from fully self-supported to aid-supported is worth planning around: it is a natural point to resupply and reset before your final push to the finish.
The race director's own guidance is worth taking seriously here: faster finishers benefit from the standard 9 PM start, while runners expecting a 9 to 11 hour finish should plan a later start closer to midnight so the marathon aid stations are open for their final miles.
Because start time options vary by predicted finish, confirm your own timing directly with Les Wright before race day rather than assuming everyone goes off at 9 PM. Starting too early relative to your pace means arriving at a finish line that is not ready for you; starting too late risks running short on the aid support available for your final stretch.
A road ultra removes the grade-adjusted pacing math of a mountain race, but darkness, temperature swings at lake elevation, and 48 miles without aid change the equation just as much. Set a pace you and your crew can sustain through the coldest, darkest hours of the night, since that is where most self-crewed ultras go wrong, not in the daylight miles.

With zero race-provided aid for the first 48 miles, your fueling plan is only as good as your crew's ability to execute it in the dark, on the side of a mountain road, at 2 AM.
Aim for roughly 60 to 90 grams of carbohydrate per hour, and hand your crew a written, hour-by-hour plan before the race rather than trying to communicate changes on the fly overnight. Since there is no aid to fall back on for the first two-thirds of the race, treat any gap in your crew's access to you as a gap in your fueling, and plan meeting points accordingly.
Keep sodium in the 300 to 700 mg per liter range, and plan for real temperature swings between the evening start and the coldest pre-dawn hours at Tahoe's elevation. Warm layers matter as much as fueling on a course like this: have your crew ready with a jacket and dry gear at scheduled stops, not just food and water.

It is a genuine ultra, but its difficulty comes from distance, darkness, and self-support rather than technical trail. You run 72 miles counter-clockwise around Lake Tahoe starting at 9 PM, mostly on paved road and shoulder with a few bike paths, and the first 48 miles are entirely unsupported, meaning you provide your own support vehicle and crew. Combine an overnight start, a stretch of narrow road shoulder including a 40 yard tunnel at Cave Rock, and 18 hours on your feet, and this becomes a serious test of logistics and mental toughness even though the terrain itself is not technical.
Not really. The course runs on the road, with a few bike paths used whenever possible, including a newer bike path off the road near the Sand Harbor boat entrance. There are narrow shoulders in several places, especially the tunnel at Cave Rock (about 40 yards long) and the stretch between Glenbrook and Spooner Summit. Treat this as a road and night ultra around one of the most scenic lakes in the country, not a technical trail race, and plan your shoes, pacing, and mental approach accordingly.
From the 9 PM start at the Golden Nugget Casino Hotel until roughly mile 48, where the course joins the Lake Tahoe Marathon route, you and your crew are entirely on your own. All runners must provide their own support vehicle, and support vehicle personnel are allowed to support up to 3 runners maximum. The first few miles have streetlights through Round Hill and Zephyr Cove, but past that, plan your own lighting, water, food, and warm layers for a genuinely unsupported overnight stretch on open road.
With no aid stations for the first 48 miles, your crew is your entire fueling plan until the course joins the Lake Tahoe Marathon route and its aid stations for your last stretch. Aim for roughly 60 to 90 grams of carbohydrate per hour, and keep sodium in the 300 to 700 mg per liter range, planning for a genuine overnight temperature swing at lake elevation rather than a single hot afternoon. Brief your crew on your fueling schedule before the race so they can execute it without you having to think through the math at 3 AM. Build your numbers with the free ultra fueling calculator before race day.
The race carries an 18 hour time limit from the 9 PM Saturday start, with official timing ending at 3:00 PM Sunday. The race director notes that runners finishing in the 9, 10, and 11 hour range should plan a later start closer to midnight, so they have the Lake Tahoe Marathon's aid stations available for their final 26 miles and do not arrive at the finish before it is ready. Confirm your own start time and any staggered-start options directly with the race director rather than assuming a single fixed 9 PM start applies to every finisher profile.
Not as a true first ultra. The distance, the fully unsupported first 48 miles, and the overnight start mean you need real experience crewing and fueling yourself before you take this on, even though the road surface removes the technical trail risk of a mountain ultra. It suits an experienced ultrarunner looking for a genuinely different format: a long, self-crewed road effort at altitude around one of the most scenic lakes in the country, rather than a beginner-friendly buckle race.
