Event Description:

Saturday, August 26 2017 is the eleventh annual XTERRA Iron Creek, part of the XTERRA America Tour. Thirteen miles from Spearfish, SD, Iron Creek Lake is nestled in the northern end of the beautiful Black Hills of South Dakota.

The course features a 1000m swim, 20k mountain bike and an 8k run. The swim is a spectator-friendly, two-lap course, with a short exit between laps, at scenic Iron Creek Lake. The ride climbs from Iron Creek Lake up to the Old Baldy trail system in the Black Hills National Forest. The ride is entirely within forested areas, so bring your technical skills and expect lots of single-track. After descending back to Iron Creek Lake, the race goes to a challenging two-lap run around the lake, where spectators cheer on the racers as they tackle difficult hike sections on each lap of the run.

Iron Creek Lake's cabins and camps sites are available race weekend. Spearfish also has many great hotels and restaurants and is near gambling in historic Deadwood, the great carvings of Mount Rushmore and Crazy Horse, the 114-mile Mickelson trail and countless miles of single-track.

Race Categories

Solo - Standard solo triathlon. No sharing, keep all the fun for yourself. Either Normal XTERRA distances (1000M Swim-20K Bike-8K Run), Sprint distance (500M Swim-10K Bike-4K Run), Mudder (500M swim-20K Bike-8K Run) or Landlover (4K Run-20K Bike-8K Run)

Relay - Relay Team Race. Two and 3 person teams allowed. All female teams will be scored female. All male will be scored male. Mixed Relay will not be scored. Relay teams may use a swimmer from the solo race (must register solo and relay separately).


The quickest way to access Iron creek Lake is to take Exit 8 off Interstate 90 on the west edge of Spearfish and head south. McGuigan Road turns into Tinton Road a couple miles south. After traveling about 13 miles south, a wooden sign will indicate where to turn right or west onto Beaver Creek Road. Just a half mile or so down this road, and another wooden sign marks a left-hand turn onto Iron Creek Road which leads directly to the lake.

The lake can also be accessed from Spearfish Canyon by following the signs just west of Roughlock Falls.


Iron Creek Lake has campsites and cabins for rent. This is the ideal place to stay for the race, but space is limited so reserve you spot quickly. The next best is to stay at one of the many hotels in Spearfish.
