NEW CLUB DYNAMIC ACTIVITY
By: Ian F Date: February 4, 2025, 5:14 am
---------------------------------------------------------
At the end of the 2024 season, several of us experimented with a
new dynamic activity. This is titled as a CKGB
Endurance/Reliability Trial.
However, this does require experienced drivers due to the amount
of overtaking that may be involved. Therefore, we may have
alternative non-timed practice sessions for the less experienced
drivers.
This is not an event to find the fastest cyclekart, it is an
event to find the most reliable and consistent cyclekart/driver
combination. Please be aware that this is not your usual CKGB
event, where most people generally run for a total of perhaps 40
minutes throughout the day. During the trial, you will probably
be on track for a total of 80 minutes or more, spread across 8
or more sessions.
Thanks to the probable numbers attending the Stretton event on
25th March 2025, this is planned to be the first formal CKGB
Endurance/Reliability Trial. Electronic timing transponders
will be issued on the day to enable the accurate collection of
timing data to work out the results. More detail on this event
is at

A more detailed description of the format for the trial is in
the attached document

Can I suggest that the club evolve a protocol for drivers where
there are significant pace variations. From several decades of
driving competition cars I know what I am used to, others have ,
in the past, been critical of that.
Hence I believe that the club needs to set this down.

The ethos of the club is that it is a constructors club, where
we sometimes have activities to see how they perform. We are
not a racing club. Our dynamic activities are based around that
ethos, consequently we expect "gentlemanly" driving.

I really like the sound of this !
It should give a good indication of:
Machine Preparation, Performance and Reliability.
&
Driver ability to lap consistently and get through traffic (and
Understand Flag Signals) !
When Calculated, its a good measure of who was OVERALL, Best
Driver on the Day !!

Glad you like it. I think its fair to say that all who took
part in the experiments thoroughly enjoyed themselves. Just be
aware that its a long but fulfilling day keeping your cyclekart
running for all the sessions. The fact that we have four
different layouts to run at Stretton also contributes to a very
varied day ;D
The Performance Index means that you dont need the fastest
cyclekart to get a good result 8)

I agree Ian, however this activity is going to create
overtaking. As an example the "usual" is that in the overtaking
manoeuvre it is expected that the overtaking driver has
responsibility for completing it safely. The overtaken driver
should take the "line" that he would take if there were no other
car on track, and hold that line.
Is that the expectation of the club, or the other option that a
slower car should pull aside to allow the other through on their
chosen line?

Rhys, before jumping to conclusions around the event, perhaps it
would be wise to witness it first hand. On the day, marshals
were instructed to use the flag system to make the slower
drivers (Me, look at the results) aware of upcoming traffic, and
we were instructed at brief to keep the racing line while
allowing passing traffic through (No deliberate blocking).
This format is more likely to bring victory to slower drivers in
two ways.
1. As you don't overtake anything as the slowest on track, your
racing line is always clear.
2. You are not driving on the ragged edge for victory, slower is
more consistent as you make fewer mistakes in line.
The rest is down to reliability of your car. I took the day not
with all out speed, but humming classical tunes to keep rhythm
and time (Think a slow waltz rather than the ride of the
Valkyries).

Rhys, this topic isn't really the place to be post about
overtaking. However, here is a brief explanation. Each event
has its own risk assessment and the Clerk of Course for that
event is responsible for the safety of that event and will brief
accordingly depending on the activities, the venue and the
prevailing conditions.
CKGB have a Hazard Log and a risk Management Plan, plus
supporting event management documentation, to aid and guide
event officials. There are risks arising from overtaking and
cyclekarts have open wheels, no bumper or side protection, and
may be driven by inexperienced drivers. Consequently, the risks
from overtaking have to be managed. Within CKGB we have general
practice sessions so people can get accustomed to their
cyclekarts and the types of tracks we run on. Once we get into
friendly competitive activities then we start with sprints (only
one cyclekart at a time) and then pursuit racing (two cyclekarts
racing against each other but no overtaking). The next stage is
the new Endurance/Reliability format, with multiple cyclekarts
on track, but with a rolling start and drivers setting whatever
gap they are comfortable with from the faster one in front.
Overtaking does not normally occur till the end of the session.
Blue flags may be used to warn of the proximity of other
drivers.
All dynamic activities have a safety brief (including
overtaking) before they start.
My personal concern is the awareness that drivers have of
others. Helmets (especially full-face) limit peripheral vision,
plus some less experienced drivers have a very narrow field of
vision and seldom move their heads to see who is close and in
what position. Consequently, during the latter half of 2024
(for events I was running) I introduced an oval layout with a
double parallel course along one of the straights. The parallel
tracks had gentle merges, and this layout prevented bunching of
drivers and facilitated safe overtaking. It also got drivers
into the habit of turning their heads to see if anyone was close
to them before turning into a corner (you could literally see
their heads swivelling on their necks).
So in summary, overtaking is duly considered, and a relevant
brief is given at the event.

Thanks Ian, one of the events I was at in the US did something
similar where there was a series of cones marking a centre line,
if you wanted to overtake the person in front, you just chose
the other lane. Initially it seemed a bit odd, but did work.

If the driver of a 10hp/35mph kart can't be entrusted to
overtake appropriately and safely I hope they're not actually
out there with a driving license...
