Fort Collins Trail Runners


The Fort Collins Trail Runners group is not a formal club. We are simply a group of local runners who enjoy running trails for fun, training, and/or racing. Any group run “leader” is simply a facilitator who offers an announcement for a group run or other activity. Participants in any group activity are responsible for their own safety and enjoyment. We do not require any membership dues and participation with the group is entirely voluntary.

Weekend Group Training / Fat Ass Events

Among other impromptu runs, we have a couple of favorites that we try to get done every year. The spring vertical series of runs are geared more towards the ultra inclined, but they can all be adapted as shorter runs. These have been designed to maximize sociability and shared suffering.

Spring Vertical Series

March Mileage Madness (Essentially a circumnavigation of Horsetooth Reservoir with routes from 21 miles to 36 miles. Shorter options available. BBQ at the Mays after) – Date TBD

Round Up (30 miles, 10,000 feet of elevation gain, one mountain) – Date TBD

Crosier Triple Bagger (26 miles, 8,000 feet elevation gain, three Crosier summits) – Date TBD pending construction schedules on Hwy 34

Quad Rock Preview (25 miles, 5,700 feet of elevation gain) – 4/7/2024

Greyrock 6-Pack (6 Greyrock summits. 46 miles with 16,000 feet of gain. Not for the faint of heart, but there are bomber, doubles, and 4 packs up for grabs too) – Date TBD

Other FCTR ‘Events’

24 Hours of Towers (one hill, 24 hours, you decide how many summits) – Date TBD

El Chubbo Grande (FatAss ‘Race’ in Horsetooth Lory. 31 miles – 7,500′, 25.5M – 6500′, 21.5M – 5500′) – Date TBD

Time Trials

Every other Thursday evening we meet for a handicap time trial ascent. Towers Road is the usual route but we occasionally run Horsetooth Rock, and there has also been talk of taking the time trials to other popular ascents in the area, including Arthur’s Rock, Greyrock, and Round Mountain.

**The 4/19 time trial will be held on Horsetooth Rock starting from the upper Horsetooth Trailhead at 6pm.

Unless we announce otherwise, this is the regular Towers Time trial plan:

Start: Soderberg Trailhead at Horsetooth (The lower trailhead off of Shoreline Dr)
Time: 6pm is the standard 50min ascent start. If you think you need more time to get to the top, plan to start out a little earlier.

Everyone starts out based on their best estimated ascent time with the goal of getting everyone to the top at approximately the same time. After we regroup at the top, we jog back down at a casual pace.

The official Towers start is the trailhead sign next to the bathrooms. The finish is the corner of the building across the clearing at the first set of towers (left fork at the top). The route is 3.4 miles to the top with about 1,700ft of climbing.

Vert Stats:

Start: 5459′
Finish: 7146′

Vertical feet per half mile:

0 – .5 (Swan Johnson Trail + a tiny bit of Towers) = 89′
.5 – 1 = 341′
1 – 1.5 = 301′
First full mile on Towers = 642′

1.5 – 2 = 278′
2 – 2.5 = 128′
Second full mile on Towers = 406′

2.5 – 3 = 350′
3 – 3.4 = 195′
Last .9 on Towers = 545′

Towers April 5: 14 out of 22 PR

Posted on April 6, 2024 by nick
The spring PR season is clearly in full swing. Last time out we had 13 personal bests, but this time up we went one better with 14. When will this madness end? There were a total of 26 runners, 4 new and 22 returning, which means a PR strike rate of 64 percent.

Off the charts!

Perhaps the most notable PR of the night came from one of The Hill’s most loyal customers. Alex May has been toiling away on Towers for two years now, so you’d think personal bests would be marginal at this stage. But oh no, how about a huge 90 second PR, people!?

It took a slight revisit of his lunch, but Pete Stevenson wasn’t far behind Alex in the outstanding-run-of-the-evening award. The bearded one sliced almost a minute off his PR for an impressive 31:31. Also impressive was Brian B who put up a fourth PR in a row, and then we had Burch, Elijah, Katie and Mike E putting up their third consecutive bests.

Virtual insanity!

We move to the upper lot for a run at Horsetooth Rock in two weeks. See you there!

Towers 3/23: 4 Under 30, 13 PRs

Posted on March 23, 2024 by nick
The ice was all but a distant memory, the wind was barely noticeable, the temperatures were in the high 50s, and we had daylight the whole way up. With (almost) perfect conditions for the first Towers time trial of the spring season, we had a record 13 runners register personal records, four guys run under 30 minutes, and the issuance of a serious threat-down from Steph Lynn to Jenn Malmberg’s FKT.

In total, 34 runners started out from the Soderberg trailhead, six of them new to the hill, which means 46 percent of the Towers veterans posted a PR. Impressive stuff folks. And we still have six determined runners batting 1.000 for 2024.

We’ll be back to do it all over again in two weeks.

Towers 3-9-2024

Posted on March 9, 2024 by nick
The conditions on Towers were about as good as we’ve seen them all year, but still less than ideal, with a few scrapings of ice in the usual shaded corners and additional snow and ice up high. Fully 20 percent (4) of the 20 who started out from the Soderberg trailhead reached the summit in personal records, which I guess shows how good the track was (or just how fit these specimens were) last night.

This was the last lights-required Towers TT of winter and we were treated to a huge and very orange full moon off to the east as we made our way down, so lights were in fact optional. For the next one, conditions should be stellar and hopefully people will be cranking PRs left right and center, and maybe we’ll sprinkle an FKT or two in there too.

Towers 2-23

Posted on February 24, 2024 by nick
Another 18-runner (one-dog) turnout on Towers last night. While the conditions underfoot were distinctly winter-like, runners started off without the need for headlamps and then enjoyed the transition to a beautifully clear and starlit night. Another couple of Towers sessions and I think we can leave the headlights at home – a sure sign that we’re turning the corner on winter.

Conditions ranged from dirt, to ruts, to crunchy ice, to a dusting of snow, to inches of snow, to knee-deep post-holing. A real mixed bag for sure, but way better than last time out, I am told.

We’ll have another 15 minutes of daylight for the next outing on March 8, in addition to a full moon. Headlights optional?

FCTR’s at the Moab Red Hot 55k/33k

Posted on February 21, 2024 by Pete
The Fort Collins Trail Runners had another strong showing at the Moab Red Hot 55k and 33k races this last weekend. By my best count, we had 43 FCTR finishers. A few people had a rough time out on the slickrock but everyone who started made it to the finish line. Sarah Hansen placed 3rd in the women’s 55k in her first ultra. Maggie, Lindsay, and Dave Seabeck also finished their first ultras this weekend. Alex, Brain Walter, Cat, and I ran new Red Hot PR’s. And we had quite a few runners out on the Moab trails for the first time. I’m sure I’ve missed some highlights so if anyone has additional results or race reports to share, send me an email with any additional details.
