TIME & PLACE: 8M race starts at 8:00 am. KIDS RACE starts at 7:30am. Starts/finishes at 299 Old Edgemoor Drive near Oak Ridge TN. Google Maps Link to Start.
COURSE DESCRIPTION: This 8 mile course will do some climbing early and offer good flow the balance of the run through Haw Ridge Park, with quite a bit of it along the lake, before returning to the finish line.
KIDS TRAIL RUN: Course will be almost all on trail, almost exactly a mile, and way more than a mile's worth of fun! As those who ran it last year can attest, it's a really, really good course.
REGISTRATION AND FEES (NO REFUNDS AND NO BIB TRANSFERS): Registration fees above, KTC member discount accepted. Not a member of KTC? Sign up here!
SPECIAL SERIES REGISTRATION OFFERS: Sign up online for 7 for $109 Season Pass, or Kids 7 for $29 Kids Pass bundle deals and SAVE BIG! Trail Series Bundle Expires June 1.
T-SHIRTS: Special limited edition T-shirts will be printed for the series. This is the same shirt as at all other Treadin’ Trodden Trails races; one shirt per runner PER SEASON please. Taking multiple shirts minimizes monies we are able to donate to trail friendly causes.
TTT SERIES AWARDS: This year we'll be awarding the top 3 in each division free race entries. Additionally we'll hold a drawing so that two lucky runners get a pair of shoes, thanks to the generous sponsorship of Runners Market. We'll once again be presenting the awards at the annual KTC Holiday Party in December. Reminder, to qualify for series awards (and free shoes!), you'll need to be a member of KTC, and you will need to have volunteered two times during the course of the trail race season.
RESULTS: Results will be available on this RunSignup page at the Results link.
COURSE ETIQUETTE: We reserve the right to disqualify anyone who exhibits unsportsmanlike conduct or is abusive to volunteers. Due to insurance regulations, no headsets, earphones, bicycles, baby strollers, roller blades or pets on the course.
SAFETY: One aid station will be set up roughly halfway through the race at a lakeside picnic table. There will be a limited supply of very small cups, so we urge you to carry your own hydration container. We also strongly recommend that anyone sensitive to insect stings or bites carry their own medication. Finally, we urge that everyone do some pre-race training offroad, as there is no substitute for experience. We want you to have a good time.
SAFETY POLICY CLARIFICATION: Our primary goal is to keep everybody safe out there in the woods. We've had some interest by younger folks in running the longer races, and we're all over that idea, but we are also concerned about their safety. If a runner is under 12 years old, he or she will need to be accompanied by an adult in order to run the adult race (i.e. not the kids mile). Also, and this is less of a safety concern and more of a concern for the welfare of our volunteers: we'll enforce the 18:00/mile minimum pace. This has been our policy all along but we've gotten a little lax and this keeps our volunteers in the woods far longer than they should have to be. Moving forward, each race will have a sweeper, and runners will need to be moving at greater than an 18:00/mile pace to stay in the race. Don't get caught by the sweep!
DON'T TAKE A BIB IF YOU'RE NOT RUNNING. This is safety-related - we want to make sure that everybody who starts the race stays safe. If you take a bib, we think you're running the race. Then when you don't show up at the finish, we have to try and track you down and make sure you're not lost in the woods or hurt. So please -- if you're not running the race, don't take a bib. Also, if you have to drop out of the race, please let one of the race officials know so you are accounted for. Also, don't crunch or fold the bib, or tear off the bottom. We need an unspoiled bib to record your time and finish place.
INFO FOR VOLUNTEERING: We love our volunteers! Please connect with us if you'd like to volunteer ([email protected]), and you can find openings at the "Volunteer" link above.
KTC SAFETY POLICY: The Knoxville Track Club Board of Directors has approved an Event Safety Policy, viewable here: Weather Policy. Please familiarize yourself with it.
Trail Camp for Big Kids
Have you ever been jealous of all the kids who get to go on camps every summer? It sucks being a big kid with responsibility but here at the annual Trail Camp for big Kids, we are now inviting you, the big kid! This camp will focus on a variety of things, team building, navigation, community service, friendship, and of course a bit of running!
Trail camp is for adults to get away from the busyness of life and a chance to play in the mountains for a long weekend. This camp welcomes all levels of runners and even non-runners! Camp consists of sharing campfire stories, trail stories, bad jokes, and miles throughout the forest. Camp is a no-pressure weekend so you are welcome to run as much or as little as you like.
Welcome to Trail Camp for Big Kids! This long weekend is meant to be relaxed and fun with some running mixed in! We are headed back to Rattler Ford Group Campground in the Nantahala National Forest!
You are welcome to run as much or as little as you want! It is completely up to you. We will have some planned runs and we can split into groups that will stick together! All paces and abilities are welcome and we will not let people run on their own (unless they want to and are comfortable with it). The weekend schedule will be loose but follow the structure below.
If you have any dietary restrictions, please plan to bring adequate food for yourself. We will try to offer vegetarian/vegan options but when planning for the masses, this can be difficult!
NOTE: Carpooling will be VERY helpful. There is limited parking but we can park cars approx 10-12 miles away at the Nantahala headquarters. Please plan to carpool with at least 1 other person! 2 if possible!
