Series Long Classifications

This year, there are two series long classifications - Best All Round (BAR) and Age Handicap. Note that the age is based on age as of December 31st of the current year.

The final series results will be computed from the OBC's time trial database one week after the last event of the season. Corrections will not be accepted after that date.

Best All Round

  • Qualifying events are the OBC 15km Open and Woman's time trials, and both OBC and Almonte Bicycle Club 40km time trials.
  • The classification is based on the average speed of a rider's best 15 km result and best 40 km result
    • Example: best 15 km time = 21:30 = 41.86 km/h, best 40 km time = 57:00 = 42.11 km/h. BAR result = (41.86+42.11)/2 = 41.99 km/h
  • Ties will be broken by the fastest 15 km result. If still tied, a tie is declared.
  • Club trophies are presented to the top male and top female
  • A medal will be presented to the top three riders in each racing category (including the top male and top female)

Age Handicap

  • The classification is based on the sum of a rider's best 3 handicapped times from the 15 km open series.
  • A rider's handicap (time deduction) is calculated from the following table 
Age Handicap in seconds
<16 2:30 (i.e. riders under 16 may enter but will have no age advantage)
16-18 20 seconds + (19-age) * 30 seconds
19-22 (23-age) * 5 seconds
23-39 0 (no handicap)
40-59 (age-39) * 5 secs
>59 1:40 + (age-59) * 8 secs
  • Example: Jane is 42 years old on December 31st. Her handicap is 15 seconds. Mary is 50 years old; her handicap is 55 seconds. Jane's best 15km times are 22:05, 22:15 and 22:20. Mary's best times are 22:30, 22:35, 22:40.  
    • Jane's handicap result is (22:05+22:15+22:20)-(3x0:15) = 66:40 - 0:45 = 65:55
    • Mary's handicap result is (22:30+22:35+22:40)-(3x0:55) = 67:45 - 2:45 = 65:00
    • Mary is ahead of Jane in the series
  • Ties will be broken by the holder of the lower handicap, and if still tied, a tie is declared.
  • Club trophies will be presented to the top male and top female
  • A medal will be presented to the top three male and female riders (including the top male and top female).

Best 3 15km

  • This classification is based on the riders best 15km results from the OBC Open and Woman's Time Trial Series
  • Medals will be presented to the top three riders in each age category. 

Age Categories

We use the standard CCA (Canadian Cycling Association) racing categories, which use age as of Dec 31 of the current year

  • Master A = 30 to 39
  • Master B = 40 to 49
  • Master C = 50 to 59
  • Master D = 60 to 69
  • Master E = 70 to 79
  • Master F = 80 to 89

We also have

  • Minime = Under 15
  • Cadet = Under 17
  • Junior = Under 19
  • Senior = 19 to 29

Insurance Details

As we have all learned, insurance has become a big part of organizing cycling events and members need to understand that they will not be able to participate in club events unless they can demonstrate that they are members in good standing at the time of the event.

Insurance requirements have for several years forced the OBC to adopt the following participation rules for the club's Time Trial Series. OBC members can ride for free as usual. However, there is no trial period for non-members.

Before you can ride an time trial, you must provide proof that you are EITHER:

  • a member of the OBC or
  • a member of another club affiliated with the Ontario Cycling Association.

Non-OBC club members must have a copy of their OCA membership card in order to ride.

Unfortunately, because Quebec does not use the same insurance policy as the OCA, this means that members of Quebec-affiliated clubs will have to join an Ontario club if they wish to participate. Naturally, we hope that club will be the OBC.

Holders of an OCA membership who choose NOT to join the OBC must pay a $30 fee to participate. As in recent years, there is no per/ride option. This decision was made to reduce the administrative work that organizers have to perform at each event.


  • OBC Members Free!
  • Non-OBC Members are $30.00 for the season with proof of current OCA membership.

Due to OBC and OCA insurance rule changes, pay as you go rates are no longer available.

See Becoming a member for OBC membership on-line registration.


The series is run by volunteers and as such we are always looking for extra hands to help out. Devoted partners and friends are needed as time-keepers, bike holders and course marshals. All riders are encouraged to recruit new participants and volunteers, or by helping out themselves.
