The Lost Soul Ultra Marathon will take place September 7-8, 2018 in Lethbridge, Alberta. Annually, it is the weekend following the Labour Day holiday weekend. The event has been filling up in a few hours and registration is in January.

The 100-mile and 100-km events start at 9:00am Friday morning with 33 and 21 hours respectively to finish. The 50-km event starts Saturday at 7:00am with 11 hours to finish. The trail course runs through the city's river valley coulees on public and private land. In this event, 320 ultra-marathoners race against each other, the elements, and the unrelenting hills. Less than 150 years ago, these valleys were the site of the last major First Nations battle on Canadian soil between the Blackfoot and Cree Confederacies.

The course resembles a pair of stacked figure-eights. The three aid stations are located at the intersection points with segment distances varying from 7 to 16 km. Elevation gain or loss is approximately 1000 metres with 13 significant hills over the 53km loop. Although we are on the prairies, our river valley can feel like the Grand Canyon. Top race times are around 5 hours for the 50k, 11 hours for the 100km and 21 hours for the 100-mile event.

The race organizers continue to keep the race small to maintain memorable running experiences. One racer commented: “Thank you to all the organizers and thanks and hugs to all volunteers, you made it possible for me to finish and enjoy spending time at each station. I will be back next year for sure.” Check out our Facebook page to read more racer comments and reports.

Lost Soul Ultra...I ran the 50k in 2014 and 2016. Plan on going back in 2018 because it's amazing!!! Such a great atmosphere, awesome and challenging course, fantastic aid stations and volunteers. Best organized race I've ever done!

When the registration opened I had an ipad and a laptop going to ensure I got in as I had waited too long the previous year. Like many ultrarunners I have always wanted to get in to WS100, although for me this dates back to the 80's when endurance sports were not mainstream and had more cult figures like Ken Shirk aka Cowman A-Mooha
I got in this year and began the serious training cycle in the spring. In June at the WS100 pre race meeting, I won a raffle entry into 2018 WS - I now only had to complete a qualifier and I had fortunately entered in to one!
I managed to stay healthy through the summer but battled 35-40 degree Okanagan heat with more often than not heavy smoke in our valley. In our area this lasted on and off for 6 weeks - who knew it was race day condition training at its best. I made one trip to Lethbridge in mid July - hit some great mid-30's weather and was able to get in a couple of decent training runs. My wife and I drove our van to Lethbridge (opted not to camp down by the river) and got ready for race day. Thursday check in was smooth - lots of great people working the table and milling around. Friday morning came quickly and we were off. My wife and I had made a detailed plan of meeting times based on a 18 hour finish time. Through the hot afternoon I slowed my pace keeping focus that all I needed to do was to finish as I didn't want to risk my WS opportunity. The aid stations were always a high point throughout the day and night with so many encouraging and eager to help volunteers. In my opinion this is one of the best race volunteer groups I have seen in action. The course met and exceeded expectation. Having trained in heavy smoke and heat seemed to have helped as I was fortunate that I did not have any issues from it. A very challenging, but well marked and entertaining race route! I managed to finish in 19 hours. Thanks to the race organizers and all the amazing people that make this event happen. Be proud of what you have.
Side note - I have promised my wife that I will retire from endurance events after WS, but I do have a certain day in January marked on my calendar - we will see. To anyone who wants a great race experience and to challenge themselves with a tough course - check out the Lost Soul Ultra.

Amazing race! I ran the 100k in 2016 as my first 100k, and came back in 2017 for the 50k. It has the best aid stations, hands down. They have everything and anything you can imagine. The race swag/shirt is always really high quality. Don't underestimate the difficulty of the course, the coulees are challenging and the temps are often hot. It's all worth it though for the awesome community and great weekend of running!

2017. My first ultra. OMG. Why am I doing this? So much fun. So hard, hot and smoky. It seems this run is trail running with Tourettes ;-) You get to the bottom of a hill and start swearing under what is left of ypur breath! The crew is fabulous, friendly and helpful. The aid stations are fantastic and have everything to keep you going.

I have ran the Lost Soul Ultra 100K the last 3 years (2015-17) and really enjoy the event! Most of my racing is in the mountains in NW USA so running a race on the prairie & in the Coulees is a nice & challenging change of pace. Due to the course layout its a great course for support & spectating and the race organizers do an incredible job! My only compliant might be that it was a tad bit hot, dusty & smokey this year. But I hear the HVAC crew is on it for next year! :)

LSU was my first Ultra, when I completed the 50K back in 2012. I've gone back almost every year since! The race directors do a great job organizing the event, and the volunteers are always amazing! The aid stations are stocked with a lot of great food options, and a lot of support. The course is challenging, but the cut-off times are generous enough to give slower runners, like myself ;-) , a fighting chance. Expect a lot of steep hills, mixed in with runnable sections, and hot weather during the day.
The race has gotten so popular that it sells out within a few hours, which speaks to what a great event it is!

My opinion might be a tad bias as i live in Lethbridge and know the folks that host this race very well. But that is the reason i chose LSU to be my first ultra. The course is my own backyard for starters so training was fantastic! Because i know the folks involved and a volunteer previous to running this ultra i knew it`s a first class race. If you get the opportunity to do this.....do it!

9/9/16 ran the 100k
Absolutely amazing event. Challenging course for those not accustomed to running the Coulees. Incredible support from start to finish. Great aid stations, post race breakfast, fleeces and personalized tiles for finishers. Already planning on coming back next year.

Ran 100k in 2016.
Amazing race. Tough course but generous time limit. Aid stations are great and the volunteers are even better! I would definitely do it again.
