Well, fortunately, stepson got a lift to his rehearsals and back. Unfortunately, on Saturday afternoon, MrsC dropped a paving slab on her foot and had to go to the Minor Injuries Unit. As the X-Ray department was shut, she had to go back on Sunday at 11.00. However, as she was determined that her foot wasn't broken (4th metatarsal, as it happens), she insisted that I attend the marshalling day...
So, I got up at quarter to six, made a thermos and wrapped up warm and arrived at Castle Combe to sign on at quarter to 8.
It was packed with over 100 blokes in orange suits (it's the new black, apparently), there to take one of their periodic, mandatory training courses - and 30 of us newbies.
We were issued with 2 vouchers for hot drinks from the canteen and one for a light lunch, which was a nice touch, considering that the course was entirely free.
The training began in earnest at 8.30, with a PowerPoint presentation delivered in the Wiltshire College building (the college offers a motorsport engineering course, so has a facility on the circuit).
Although there was a fair bit of "death by PowerPoint" as the trainers called it, the information was delivered with such professionalism and enthusiasm that I never found it dull.
After the first session (on marshalling generally, equipment, the various specialisations, hierarchy, etc.), we had a really informative 45 minutes with the Scrutineer (senior, MSA accredited), who walked and talked us round a couple of Formula Ford cars and a circuit-prepared Fiesta in the college garage. Lots of interesting and up-to-date info on helmets, newly-compulsory HANS devices, seats going "out-of-date" and not deploying fire extinguishers instead of electrical cut-offs.
We then broke for coffee before a presentation on fire theory and the medical centre.
The free light lunch was followed by a bit of practical first aid drill (recovery position, CPR) combined with the problems associated with casualties in helmets/trapped in cars/covered in fuel.
Next was a practical demonstration of how to roll a car from its roof to its wheels as gently as possible to avoid exacerbating neck injury (not sure what non-motor-racing Health and Safety would have made of 12 blokes with no PPE or training, grappling with a car on a steep grassy bank - broken windows, ripped bodywork and all...).
After that we were led on foot up the circuit to Marshal post 2, (between Folly and Avon Rise, for those that know the track) to see the aftermath of an accident from the previous day's track day. A chap in a fully race-prepped Audi R8 clipped the back of a Caterham at over 150mph and skidded, flew, cartwheeled and lost 3 wheels in the process of transforming his car into a bit of a state.
Pretty skid-mark patterns (compared with the ones in the driver's race suit, I imagine)

See how far the R8 moved 8 of these 8x8 Armco supports...
The marshals said it was one of the most dramatic smashes they've seen in over 30 years and that the driver was incredibly fortunate to have escaped with his life.
As it was, he was unconscious for over 5 minutes and needed some pretty extensive treatment at the medical centre, but apparently with no serious injuries. His proper race cage was credited with saving him.
A reminder that "Motorsport is Dangerous", though the marshal's post was entirely unscathed. Reassuringly.
The next part of the course was using powder and foam fire extinguishers to put out a fire on the test rig (again, we were able to get hands on), before a presentation on flags and flagging rounded off the day at around 4.30pm.
It was full-on, with a lot of information, but it was so well delivered that I never felt it dragging or becoming boring.
For a free day, provided by volunteers, it was absolutely outstanding - better than any training I've been given by so-called professionals in day jobs I've had.
It's certainly convinced me that I want to become more involved with marshalling. Other commitments mean I will never be able to devote every weekend to it, but it's a superb way to become involved in and get close to motorsport at minimal cost. With a bit of commitment, you can work your way up to becoming an experienced marshal, which can lead to working at F1 events (both in the UK and abroad - though competition is understandably high), Le Mans, the USA and many other opportunities.
I'd highly recommend anyone with any curiosity about marshalling attends one of these days - whether at Castle Combe or elsewhere; it's free and the amount you can learn is amazing. After that, the choice is yours.
