Running in Sioux Falls: River Routes, Trail Outings, and Race Choices

You want to run in Sioux Falls, but a trail map alone does not tell you whether to commit to the big river loop, choose a short outing from a park, or drive out for natural trails. The useful first decision is how much time and route flexibility you need. This guide helps visiting runners and new residents choose an appropriate starting point, understand public access, and compare local racing options without turning every run into an all-day project.

Understand the river trail before choosing your mileage

The city's paved network and its main loop are different things. The City of Sioux Falls Recreation Trail page lists more than 45 total miles of paved trails, while the Greenway Recreation Main Trail Loop measures 19.13 miles. That loop follows the Big Sioux River through parks, including Falls Park, as well as open and wooded areas.

For most visitors, an out-and-back is the more manageable introduction. You can select a turnaround based on your available time instead of discovering halfway around a loop that you have committed to more running than intended. A three-mile outing means turning around after roughly 1.5 miles from your chosen start; it does not require finding a named three-mile circuit.

Treat a complete loop as a deliberate long outing. Before committing, identify your start, review the current route, and decide how you would return if you needed to stop early. A loop offers variety, but an out-and-back makes shortening the run much simpler.

The trail page links an interactive map showing restrooms and detours. Check it before leaving rather than relying on an old screenshot. General trail hours are 5 a.m. to 10 p.m.; Falls Park and the Downtown River Greenway remain open until midnight. An extended downtown closing time does not extend access throughout the network.

Choose a starting point that solves your practical problem

Yankton Trail Park: a useful base for a measured outing

Yankton Trail Park, at 3901 S. Minnesota Avenue, is an official Recreation Trail access point. The city lists restrooms, a drinking fountain, accessible trail access, and soccer fields among its amenities.

This is a sensible candidate when you want to start at an identifiable park rather than negotiate an unfamiliar downtown approach. Set your distance from the access point and return along the same route. Include any walk or jog from your arrival spot to the trail when deciding where your recorded run begins.

For a first visit, choose one direction and keep the route simple. Save additional branches for another day, once you recognize the junctions. If you are meeting someone afterward, share the park name and a precise meeting location rather than saying only that you will finish near the river.

Listed amenities are useful planning information, but they do not establish whether a particular facility is operating when you arrive. Carry the water you need and confirm restroom availability if it determines whether the outing will work for you.

Spencer Park: another clear access point, with different facilities

Spencer Park, at 3501 S. Cliff Avenue, also provides accessible Recreation Trail access. Its amenities list includes a portable restroom, picnic shelter, playground, dog park, and singletrack bike trails. The city publishes daily park hours of 5 a.m. to 10 p.m.

Choose this start when its location fits your trip or when companions would benefit from the park's other facilities. Check that everyone understands where you are separating and meeting again. A park with several activities can be a convenient shared destination, but it needs a more specific rendezvous than a trail-only stop.

Keep the paved Recreation Trail and the park's singletrack options separate in your planning. Seeing both listed at the same park does not make them interchangeable routes. For a straightforward road-running outing, identify the paved access on the map and follow that route.

Downtown and Falls Park: prioritize exploration over a precise circuit

If seeing the river and Falls Park is your main purpose, build a flexible run around the downtown portion of the network. Choose a recognizable trail access point, establish a turnaround, and leave room for pauses.

Avoid assigning yourself a supposedly exact sightseeing loop without first mapping the connections. Your approach from lodging, chosen crossings, and stops all affect the final distance. A time budget is often more useful: decide when you need to turn back, then finish where you started.

Share the paved trail without making the run awkward

The Recreation Trail is a public shared-use space. The city's trail safety guidance directs users to stay right, pass left, give an audible signal when passing, and avoid blocking the path. It permits runners alongside walkers, bicycles, and other authorized users.

Apply those rules at the moments that matter. Before turning around, look behind you and move out of the travel line. When checking a map or waiting for someone, step off the path. If your group spreads across the trail, narrow it before another user has to ask.

For a run with faster sections, first inspect the stretch you intend to use. Choose a place where you can see approaching users and finish without stopping in a busy junction. If the path is crowded, a continuous easy outing is the simpler choice. Public access gives you a place to run; it does not reserve uninterrupted space for a workout.

Good Earth State Park: plan a separate natural-trail outing

Good Earth State Park at Blood Run lies southeast of Sioux Falls at 26924 480th Avenue. South Dakota Game, Fish and Parks lists year-round park hours of 6 a.m. to 11 p.m. It is a day-use park with no camping.

As checked on October 6, 2026, the official page lists daily entrance fees of $10 for South Dakota residents and $15 for nonresidents. Verify the current fee before your visit. The visitor center operates on a separate seasonal schedule, so open park gates do not necessarily mean an open building. The agency also warns that some water systems and flush toilets may close between October 1 and April 30; contact the park for current status.

Build mileage from the official trail map

The Good Earth trail map and guide identifies named routes and their surfaces. Examples include the 0.8-mile Cottonwood Loop, rated easy with a natural surface; the one-mile Ravine Loop, rated easy to moderate with a natural surface; and the one-mile Vista Loop, rated easy with gravel and natural surfaces.

Use those labels to choose the character of your outing, then trace the connections from your actual start. A named loop's length is not necessarily your total distance from the visitor center. Connecting trails and any repeated sections need to be included.

For an initial visit, pick one loop and its approach rather than linking several routes immediately. Save the map offline and note junction names as you pass them. If you add mileage, do so with a connection you can identify on the map, not simply whichever trail appears to continue forward.

Good Earth is also a significant cultural and historical site. Leave time for its interpretive features if that interests you, and keep the run on designated trails.

Find company through a current group-run listing

The Sioux Falls Area Running Club group-runs page lists a Good Earth outing on Thursdays at 6 p.m., meeting at the welcome center, from spring through late October. It also lists a seasonal Great Bear run on Wednesdays at 5:30 p.m., with a June 3–September 30 window. By this guide's October 6, 2026 research date, that published Great Bear window had ended.

Check the club's current Facebook or Strava updates before traveling to a meeting. Ask about expected distance, regrouping, and whether your intended pace fits. A meeting time alone does not explain whether the group stays together or separates into smaller groups.

The club may cancel for weather and may alter or cancel natural-trail outings when conditions are wet or muddy. That makes the latest update more useful than a recurring calendar reminder. Budget for state-park entry when joining a Good Earth run unless the organizer explicitly explains another arrangement.

Choose a race by its demands and current status

Use RaceThere's Sioux Falls race listings to compare possibilities, then confirm event details with the organizer. A familiar city name is only the beginning: distance, surface, cutoff, and start location determine whether an event fits your plans.

Two races to consider for a Sioux Falls visit

As checked on October 6, 2026, these two events have announced dates and open registration. Their event pages show the current organizer details; check them again before entering or booking travel.

The Trick or Treat Run 5K & 10K is scheduled for October 24, 2026, at Pasley Park, with running along the Big Sioux River bike path. It gives you a shorter-distance race to pair with a visit to the river trail. Choose the 5K or 10K based on the distance you want to race, and review the organizer's course map before assuming the route follows the same stretch as your training run.

For a spring half marathon, Sioux Falls Skedaddle is scheduled for May 16, 2027. The organizer describes a point-to-point route from Family Park to Fawick Park and also offers the Zippy Mile. A point-to-point race needs a different arrival plan from an out-and-back: confirm the published transport and parking arrangements as race day approaches. The mile provides another option for companions who want to take part without racing a half marathon.

Sioux Falls Marathon weekend: distinguish the next date from the previous map

As of October 6, 2026, the Sioux Falls Marathon website thanks runners for the completed 2026 event and lists September 19, 2027 as tentative. Its distance pages still display maps labeled 2026. Treat those as background while waiting for confirmed next-edition information, especially before booking nonrefundable travel.

The full-marathon page describes a USATF-certified route, a start in the large parking lot east of Howard Wood Field, and a finish on the track. Its published cutoff is six hours and 30 minutes. Compare that limit with your expected total elapsed time, including stops, and reconfirm the policy for your edition.

The half-marathon page lists the same general start and finish arrangement and a three-hour, 15-minute cutoff. The shorter distance may fit your running background or travel schedule better, but its cutoff still deserves attention before entry. Neither the greenway's everyday loop nor its park access hours should be used as a substitute for the race's official course and instructions.

Local trail racing: check which edition is actually upcoming

The club's 2026 Trail Series page lists Newton Hills two- and six-mile races for October 10, 2026, at 9 a.m. Its other listed 2026 series races occurred earlier in the year. Check registration and organizer updates before treating that October event as available, and wait for a published schedule before assuming the same dates next year.

For a first local trail event, compare the shorter option with the longer one after reviewing terrain and rules. A six-mile trail race should not be judged solely by how a six-mile paved run feels. Check the venue separately, including entry requirements and the precise race meeting point.

You can widen the search through South Dakota race listings if your dates do not match a Sioux Falls event.

Make the visit work with one primary run and one backup

Before leaving, choose your starting address, route format, and turnaround rule. Save the relevant map and confirm access hours. For a park outing, also check the entrance arrangements and any facility you are depending on.

Keep a simpler alternative ready. If your natural-trail plan is canceled because of muddy conditions, reassess a paved option using the city's current detour information. If your schedule shrinks, shorten an out-and-back rather than forcing a full loop. If you are racing, keep sightseeing miles subordinate to the event you came to run.

Sioux Falls becomes easier to navigate when you choose the outing's purpose first: a manageable river run, a deliberate long loop, a natural-trail visit, or a race. Ready to put a date on the calendar? Find your next race on RaceThere.
