2001
Contesting Cotswold Championship.
Brean Regency stages 27-28/1/01 10th overall 1st 1600cc class. An
enjoyable event for us with many of the ‘supercars’ struggling around
the twisty holiday park in the slippery icy conditions. Luckily
there was no repeat of the engine failure we suffered when a std
valve cap shattered in the 2000 event. A long break was caused by
the foot and mouth crisis losing many events.
Colerne Azimghur stages
14/7/01 15th overall 2nd in class. This is not a favourite event
for us as it is not very twisty, a lot of time was spent on the
rev limiter (4.53 cwp fitted at time)
Abingdon carnival stages
Retired on first stage with snapped drive shaft (time to change
to grp A shafts!) |

Caerwent
Patriot stages
30/9/01 8th overall 1st in class. This was the first event with
the new box and we had many teething problems. For the first five
stages we rarely had any gears apart from third. The engine however
is very torquey and this and the treacherous wet conditions allowed
us to dominate our class, this did require carrying a lot of speed
through the corners causing great entertainment for the marshals
as we had a few problems staying on the road.
Predanick City of Truro Stages
13/10/01 11th overall 2nd in class. This event was not part of
the championship but is great fun with a good balance of twisty
bits and straights. Predanick also has gravity defying levels
of grip so many corners are taken flat in top. My dad John navigated
for me on this event (his first since since the 1979 RAC rally
in a FIAT 131) as my brother was navigating for Neil Bowden in
his 1300cc Fiat Uno. Longcross on the third of December is the
final round of the Cotswold championship in which we need a finish
to win overall.
