Who are we?

NeoEndurance is an organization developed by runners for runners. We make it possible for people to look for a challenge and conquer it. Whether your goal is to run your first 5k or your first marathon, we want to help you find that inspiration. NeoEndurance empowers people to get outside and achieve that which was thought to be impossible. One achievement leads to another, and then another. Soon, you're running towards that next obstacle or insurmountable task both on the road and in life.

We're Tampa born, but love to travel. The energy of our events; the scenic nature of our courses and the fun it brings makes it a top reason to come sign up for our races. Once you're finished, come out and listen to some live music, show off your new medal, and kick off your shoes, eat some local food and hang out. Then train again for your next big race with us. Even if you're not out to compete in your age group, come out for the fun. NeoEndurance thrives on the outdoors and survives on the sweat of our courage.

5k / 10k

If you're a beginner, or simply love running, start here. Completing a 5k or a 10k are magnificent milestones and a welcoming way to love running. Once you complete a race, don't hang up your shoes. Look for another race!

Half/Full Marathons

Marathons are challenging events for a reason. It's not just the distance anymore - it's the physical and mental exhaustion you'll endure on the run. These events rely on your inner strength and on your training. Keep moving!

Ultra Runs

These are not for the faint of heart. If you've completed a marathon, then you're ready for an ultra. Ultra runners exceed expectations and defy their bodies by running 30+ miles. Choose from either 30m, 50k, 50m, or our grueling 100m.

I Finished The Boston. Time For A 50k

By Thessaly Nicolaysen

April 18, 2017: I had just returned home from the 121st Boston Marathon and met up with a friend of mine. He asked me how my 4th time running the Boston Marathon went, and I exclaimed with joy how great it was to get back into the full swing of running again! You see, in October 2016, I developed a case of tendonitis in my ankle which lasted for several months because I refused to stay off of it. Fortunately, I was able to start running again in mid-February, and was able to prepare for Boston throughout those two months. On April 9th I had run my 15th half-marathon, my first race since October, and placed 3rd in my age group. This gave me the confidence I needed to head to Boston knowing I would be able to finish strong.

While talking with my friend, I could hardly contain my excitement to run my first Ultra Marathon, which was scheduled for three weeks later, on May 13. We found out that there was a local 50K scheduled that weekend on April 23. Knowing that I was still on my runner's high, he asked if I wanted to run the Spokane River Run 50K. Of course I was on board, and we registered on the spot.

Preparing for this race was not unlike training for a marathon. In all of my racing, my training is primarily completed on a treadmill. I know, I know, "the Dreadmill?!" I absolutely love treadmill running, though. My case for the treadmill is that I am able to read, listen to music, not panic about potty stops, and have climate control year-round. The only predator I need to worry about are walkers and other gym-goers who hop on *my* treadmill before I snag it. But I digress.

Back to April 22, the day before my first 50K. Packet pickup was low-key, and it looked like I had a good chance of doing well after looking at the course map. It was a trail race, with a few steep hills and some tricky terrain. I was pumped!

Race day arrives! Thankfully it was a local race, and it started at a reasonable hour (no need for a 4am wake up). We arrived on time, and were getting the lay of the land. This course consisted of 2 different 25K loops. The first loop was definitely a challenge, but with an optimistic attitude, I was able to run/walk without much discouragement or mishaps. The second 25K loop was where I started to become a little over-confident in my ability. Thessaly2
I was running at a good pace, and after getting past the congestion of  10K and second group of 25K runners (they had a staggered start for this race, and started many of the events as the 50K runners were making their way to the second loop), I was totally alone. In some ways, I found that this was incredibly therapeutic. While I did start to slack off a little bit (its easier to justify walking if no one is there to witness your "bonk"), I was still enjoying the experience and in awe of how amazing it was to think that I was soon going to be an "Ultramarathoner." Miles 22-26 were run right by the river. There were rocks and many trip hazards, as well as a bit of hill work. As I was navigating this section of the course, I recall thinking of how dangerous trail running is, but how exciting it is! Then, just as I was thinking, "I love trail running! It's dangerous but safe enough that I won't get hurt!" I biffed it. Hard. I fell on a downhill section at about mile 26, and had a pain in my wrist, a bad bruise on my thigh, and scratched my knees and elbow pretty badly. I had no intention of quitting the race, but knew I should stop at the next aid station so they could clean and wrap my wounds. While I was continuing, I felt an immense amount of pain in my wrist. At the aid station, I had to sit for about 35 minutes (I was TICKED that it was taking so long and adding so much time to my 50K), where I took some pain killers, and asked for an ice pack to take with me to hold on my arm. The last 5 miles of this race were some of the most painful I have ever endured. I ran when I could (hobbled is probably a more accurate description), but definitely took it easier than I normally would have wanted to.

Crossing the finish line was emotional. I was in pain, but was SO proud of my new accomplishment. In my years of marathon running, I thought that a marathon was the longest distance I would ever be able to conquer. However, over the past year I have been obsessed with the thought that "maybe I AM capable of running a more challenging distance." Crossing the finish line helped to remind me that I am truly fearless, and limitless in my potential as a runner. Surprisingly, even with my fall and 35 minute pit stop, I placed 2nd in my age group! I know that there is nothing I can't do, and I recognized a new sense of strength and accomplishment as a result of finishing my first Ultramarathon.

April 24, 2017: After a painful and restless night's sleep, I decided I should probably go to the doctor to get my wounds cleaned properly and my wrist checked. An X-Ray revealed that I fractured my wrist when I fell. Incidentally, the doctor who checked my injuries ran the 50K course as well, and knew exactly where I fell. To say he was impressed that I finished the race with these injuries is an understatement. I had my knees and elbow wounds sterilized, was given a prescription for antibiotics, and was scheduled to get a cast later that week. Thankfully, I was able to run again after getting my cast because I had my next 50K in a couple of weeks...
