Time Trials

GMBC offers a free weekly time trial series that dates back to the 1970s! It is a low-key competitive event that is open to the public. The events take place every Thursday evening from early May to early September–with the exception of the last two weeks in April when they are on Friday evenings. Nearly every week a different course is visited, and courses exist in the counties of Chittenden, Addison and Lamoille. They range from flat(ish), to hilly, to mostly uphill.

Although membership in GMBC is not required for participation in the time trials, we would love to have you as a member. Every participant, regardless of member status, must sign a GMBC Rider Waiver each year in order to participate in any GMBC event. One waiver per year covers all club events. Please use the buttons below to sign the waiver or join or renew your membership.

The events start at 6:30 pm (unless otherwise noted), and to sign-up, just show up! We recommend that you show up at least 1/2 hour early so you have time to get the bike in order and to warm-up. The start-interval is one minute (in other words, every minute one rider will start), and once you’re underway, the goal is to ride as hard as you can for the length of the course and have nothing left at the finish. It’s as easy as that!

Wear your helmet at all times, share the road, be mindful of traffic, and understand that we cannot be a burden on traffic flow. Failure to adhere to these rules could result in the closing of a course due to complaints from local residents. Please find a bathroom prior to arriving, NOT at the race venue. Please remember that the roads are open to traffic and you are riding at your own risk. The race schedule is posted on the Events calendar and is also available in table form.

Last minute changes to the schedule due to weather or unexpected road repairs are announced through the GMBC email list. For more information, contact Kevin Bessett.

Local support is critical to the survival of the time trial series. Please consider showing your support of local businesses by stopping in the local store or bakery to pick up a drink or tasty treat to celebrate your big effort.

The GMBC weather manipulators (a covert arm of the club) are not always able to ensure perfect weather. Occassionally a town event or road construction may interfere with the race course. We try not to cancel races, but if severe weather or another event appears to put racers or volunteers in danger, the event will be cancelled. Only races on championship courses will be rescheduled.

What cancels races?
  • Impending thunderstorms, moderate to heavy rain, high winds, fog or impaired visibility, extreme heat (heat indexes in the mid 90s and above), or cold
    and (temperatures and wind chills below 30 degrees) are likely to cancel events. Weather radar and hourly forecasts are used for decision-making.
  • Town events such as school graduations or other events that result in pedestrians on the course and/or increased traffic, or unavailability of the designated parking area may cause race cancelation.
Race cancellations
  • Race cancellations will by made by 4:30 pm on race day and announced via the GMBC email list.
  • The most reliable way to find out about cancellations is via the GMBC email list.
  • Cancellations may be posted on Events if time permits.
  • You may try to email Kevin if it is before 5:00 pm on race day.

Riding a bicycle on the road has inherent risks. You will be riding at your own risk and GMBC assumes no liability. All courses are open to traffic and you are responsible for obeying laws. Know the course, turns, intersections and dangerous spots — such as fast descents (be sure to view the course info by clicking on the course name in the schedule)

  • A helmet is mandatory at all times; eye protection is recommended.
  • NO riding two abreast at any time; it is legal in certain situations, but not at a TT.
  • Always ride on the right side of the travel lane so traffic can pass except for areas where riding in the lane is safest (such as fast descent).
  • Show up at least 1/2 hour prior to start of event so you can assemble your bike, sign-up and warm-up.
  • Read the Instructions for Timers below to learn more about the timing and how these TTs are run.

Entering the Event

  • Just show up. There is no online registration.
  • There will be a clip board floating around with a start sheet. Just put your name in a start position (1, 2, 3, 4…).
  • The number indicates your start position and this is the number of minutes after the watch starts that you will start (for example: “11” means you will leave at the 11-minute mark).


  • Riders will be in a line waiting to start. Show up at least one minute before your start time.
  • Stay on the grass-side of the orange cones used separate you from traffic.
  • At most courses you have the option to be held — it’s a little unnerving the first few times!
  • How not to miss your start time: start a timer when the official watch starts, and that way you’ll always know exactly how much time you have left.

While Competing

  • Use extreme caution at any turn-around points (if they exist in the course)
  • If you get held up by traffic at a turnaround point, let the timers know after your finish — your time will be adjusted by how much you think that you lost.


  • About 20 meters before your finish yell your start number to the timers so they can ID you.
  • Do not crowd the timers while riders are still finishing

  • Please be familiar with the course and rules.
  • Enforce helmet usage – it’s mandatory at all times.
  • Keep riders on grass-side of orange cones at start area.
  • Remind riders they MUST RIDE SINGLE FILE at all times.
  • Riders who miss their start can go in the next free start-position–-just cross out their name and put it in the open slot, and tell them their new start position.
  • Remind riders to yell out their start position about 20 meters prior to finish.
  • Arrive at least 1/2 hour before event start-time.
  • The organizer will provide the gear and instructions. Sign-up sheet.
  • Sign-up: riders sign-up on the start/results sheet. The number to the left of their name indicates start position (for example: “3” means rider will leave 3-minutes after start of watch).
  • Starting the race: announce that you are about 1-minute from starting watch
  • Start Interval: 1-minute
  • During race: keep road clear at start/finish area(s) – we cannot be a burden to traffic (this is VERY IMPORTANT).

Recording results procedure

  • Before rider crosses the line, shout “NUMBER” to get their start position. If no number yelled, write in “?”, and if possible, note jersey color.
  • Record this in the right most column and record from the top down and by number yelled (example: 2, 1, 3, 4, 7, 5…).
  • Press SPLIT as rider crosses; the watch has a memory, so you can record when ready.
  • If several riders finish closely, press SPLIT for each one.
  • Be sure to press the button firmly.
  • The split is displayed on the watch. Click RECALL to access memory to see previous split times stored.
  • Each click on the RECALL button scrolls backwards from newest to oldest.
  • If a rider is finishing, no problem, just click SPLIT.
  • Round to the nearest second: 0.50 100ths or greater add 1 to second, otherwise use the second value on the watch.

Calculating and recording finish time

  • See example
  • Formula: Elapsed Time in Minutes – Start Position = Racer’s Individual Time      :53:03 minus 10 gives a finish time of :43:03:67:47 minus 17 gives a finish time of :50:47
  • Record in Finish Time field for the rider by cross-referencing start position yelled (this is to right of elapsed time) with Start Position in Middle column.
  • This is a little tricky. Helps leaving a finger on elapsed time and putting pen in target field.

Your fastest average speed at the Huntington (not included for 2019), South Greenish and Jonesville courses will be averaged together to come up with an overall average speed for all three courses.  Club Champions are the fastest male and female in each age category. There is also an overall fastest male and female. 

Each course is scheduled three times during the season, so if you had a bad ride at one course, you have two more opportunities to get in a better ride!

Awards are handed out at the annual club pot-luck & meeting in November.

Anyone can ride a championship course time trial, but only GMBC members are eligible to compete for awards (important note: if you are not a member by June 1st you will not be eligible to compete in the series).
