Everything you need to know about The Silver Comet Half and Full Marathon on October 25, 2025 is below!  PLEASE READ!

I am so excited to celebrate the 25th running of the Silver Comet Half Marathon and the 14th Full Marathon on October 25, 2025 with you all!!   Please remember the Silver Comet Races are grassroot, strictly volunteer races. I am a 1 woman operation. My full time job is for a greenhouse outside slinging plants in  big box garden centers.  I do not sit at a desk or access my home computer often; nor do I have access to social media pages on my personal cell phone. I don’t send emails until all details are final and confirmed so thank you for your patience as I have made all the adjustments to accommodate triple the participation this year!!

I will email this info out – then I will start addressing questions not covered here and questions from those of you coming in from out of town.

This will answer ALL of your questions. Nothing has changed from last year except the OFFICIAL START TIME of the FULL MARATHON ONLY IS 7:00AM (We did this last year and it was great for the marathoners! It will still be dark so bring your headlamps if you need one! ) and the start time of the HALF MARATHON IS 7:45am at sun up.  All marathoners must start at 7:00am to be listed in official results.  All half marathoners must start at 7:45 am.

Only other change is packet pick up place – still Wed Oct 22 & Thurs Oct 23 from 4:00pm to 7:00pm at Vinings/Smyra Big Peach (4624 Camp Highland Rd SE Smyrna GA 30082)nd w.  Hopefully this will make it much easier!

Both races start and finish at the Silver Comet Trail head located at 4342 Floyd Road, Mableton.  There will be no parking at the trailhead so please note parking below.   

Please read to the end!

Refunds/Deferrals: No refunds or deferrals as stated in registration waiver.  Run Sign Up does offer registration insurance at the time of registration.

EMERGENCY CONTACT INFO: – PLEASE make sure to legibly fill out the emergency contact info on the back of your race number.

Shirts/Medals: Yes, of course there will be shirts and medals for each pre-registered participant of the Half and Full Marathon!

Registration:  Online Registration is closed.  The race is capped at 600 participants.  I will have a wait list if anyone contacts me to cancel.

Weather: Wow! Extended forecast looks perfect. Partly cloudy – low of 52 & high of 75!

Additional Waivers: ALL Participants running the official course race day must sign the Race Day Waiver, and bring with them to packet pick up.

Number Pickup:  All local runners must pick up numbers at 1 of 2 packet pick up times – Wed Oct 22  and Thur Oct 23 from 4:00 to 7:00pm at Vinings / Smyrna Big Peach Running Company.  I hope this is easier for each of you.  Address is 4624 Camp Highland Rd SE, Smyrna, GA 30082.   outside Comet Trail Cycles 4342 Floyd Road Mableton .PLEASE DO NOT CALL THEM – They only host space for pickup and have nothing to do with numbers or times I will be there. This is number pick up only.  You may pick up packets for other participants but please bring waiver and copy of ID. Giving your number to others without proper transfer is not permitted as this makes results and awards inaccurate.  Please respect other runners by not giving your numbers away to others.  I will make official transfers for the transfer fee since we are sold out.  Anyone coming in from out of town – please contact me to arrange pickup on Friday from my home or Saturday morning.  It will only be myself handing out numbers race morning so please arrange to pick up your numbers on Wed or Thur. I will figure out how to add mailing numbers out for next year.  This is my first year with run sign up and I am learning their system.

 

Start and Finish Line Addresses: The certified start and finish line address is: : Silver Comet Trail Head – 4342 Floyd Rd SW, Mableton, GA 30126. Please remember the bike shop is still operational and the trail is not closed.  No parking is allowed at this location or on Floyd Dr. SW – the street running by the entrance and behind the retirement community and gas station.  If you park on Floyd Dr. please expect to be towed.

Parking: As with all our races: Parking is available away from businesses at the Kroger / Publix parking lots (4875 Floyd Rd, Mableton, GA)which are approximately ¾ of a mile South from start and finish line locations. Or you may park in the Walmart (1133 East West Connector, Austell, GA) or at Floyd Road Baptist Church (3996 Floyd Road) parking lot – approx a half mile North of the Race Start. There are sidewalks down Floyd road from both locations.

Do not park in restricted spaces or block business parking.  Do not park on the road leading into the trailhead (Floyd Dr. SW) parking or you will be towed.  Parking is not allowed at the TrailHead parking lot before the race start as we must leave the parking lot open to trail users.We recommend you be dropped off/ picked up at the end!  There will not be shuttles to the start.

Police: There WILL BE police at trail + road intersection closings (please see course / start line info next bullet!).   The trail is open so no headphones. Please look before crossing trail for water, before turning around – cyclists will be out in force if the weather is good.  Listen for them and don’t make sudden moves without looking behind you.

Race Course & Timing: The full marathon  will start at 7:00am (headlamps encouraged) on the trail at the finish line location 4342 Floyd Road Mableton.

The half marathon will start at 7:45am.

I do not have new course maps to view – but HERE are course descriptions with water stops and portalets noted!

Runners should be in the open area outside the Comet Trail Cycles to line up and walk down to the start line. Finish line mat will be in place at the finish line until 1:00 pm so that is your time limit for both races.  You must be in by 1:00

Boston Qualification: YES, the Marathon Course is certified and you CAN use your time for Boston Qualification. Each participant should save & send Garmin (or other GPS data) to us, for BQ verification and support.

Shuttles:  Concord Road Baptist Church, Covered Bridge Montessori School, and Floyd Road Baptist Church have volunteered their 15 person buses to  shuttle runners back to their cars after the race if you haven’t arranged pickup. Please be patient and thank them for this service!

Awards: Overall awards and top 3 age group awards this year will be awarded to those who run the certified course, based on gun time.

Course Marking: The miles will NOT be marked.

The half marathon turn around  is between Old Lost Mountain Road Bridge and the Charles Harris overpass.

The Full Marathon turn around is just past the bridge over the railroad tracks in Paulding. The route is straight out and back past the waste water treatment plant and there are no turns. The Lucille Creek offshoot has been eliminated.

The turnarounds will be clearly marked with cones and chalk paint and signs!  There will be an aid station at the Full Marathon turn around!

Water Stops: Water stops have not been moved. They  are approximately 1.5 miles apart at intersections.  We have our awesome South Cobb High School soccer coaches and soccer team members volunteering for each Half Marathon course water stop from 7:45 to 1:00. Please leave all cups and litter at the water stop for collection.  Do NOT litter on the trail.  All marathon water stops and the Turn around will also be manned. Please prepare to carry your own supplements. Marathon ONLY: Please don’t litter and keep the trail as clean as possible.

Porta-potties: The trailhead bathrooms are open and available for use. The trailheads are marked on the course map.  I added back extra portalets at three locations (Industry, County Line, and Seaboard) on the full marathon course (one – Industry Crossing – on half marathon course).  Remember that all water stops and portalets are passed going out and coming back!

Finish Line: I, Dana, will be at finish line with the DJ and our sponsors!  1st Choice Healthcare, Big Peach Running Co, Home Best Roofing, etc.  We will have bottled water, pretzels, bananas, and other  goodies. Remember packets are not available for pick up on race day – must be picked up at scheduled times. I seek a few more volunteers to help out – Please have them email me!

Photographer: Photographers will be at marathon turn-around and the finish line. These photos will be uploaded  HERE for free download after the race.  Please take selfies and photos, and send them to us, tag us on Instagram and Facebook, since you may be running all over!  Please follow us!

Spectators: You can direct your spectators as you so choose. Spectators should not congregate on the silver comet trail or crowd close to the finish line. There is an open area for lawn chairs and distance! Remember our photographer can’t get photos if spectators are crowding the finish line.

Super Excited to see you all on October 25th!

 

Happy Trails,

Dana Greene, Race Director
