  • Wear a helmet. Despite recent advances in medical science, brains still cannot be mended nor replaced.
  • Wear gloves or mitts. Hands often hit the ground first. Cuts and grazes invite infection and a hospital visit.
  • Wear eye protection, it only takes a twig or thorn to lose an eye. Crud catchers are a good idea in mucky weather.
  • When downhilling, for your own protection, allow plenty of space behind the rider in front.
  • Bring a bare minimum emergency tool kit and a spare inner tube.
  • Breakdowns are a bore. Plan not to have any by ensuring your bike is in perfect working order.
  • Punctures are also tedious. You can minimise them by fitting latex tubes, slime tubes or running tubeless tyres.

So for those planning to drive to the pub, you have your location!

I will give out A4 colour maps showing the checkpoints at the start(not A3 as MemoryMap no like! ), but it would help you to plot them onto your own map. My maps will be at 1:150,000 scale!

Each checkpoint has a score - more difficult = higher points. Scores will be given out on the night!

RULES will follow in the next post so read on....


Pasty Tom's BIG Adventure - the Rules!

Hi again all,

Here's what it's all about and some RULES!:-
1. You have a list of checkpoints to visit - they vary with difficulty and distance and you won't be able to visit them all in one night without a helicopter (which is not allowed!).
2. Each checkpoint has a score depending upon how difficult they are to get to / far they are from the finish. I will give out the scores on the night along with an A4 colour map showing the checkpoints.
3. Riders split up (pairing up is best, but solos allowed) and go off and try and amass as high a score as possible in the time by visiting either the high value checkpoints or a larger number of checkpoints or both.
4. Each checkpoint can only be ‘bagged’ once.
5. Riders/Pairs prove they've been to a checkpoint by taking a digital photo (camera or phone) when they get there. They should take a picture of the checkpoint with them and their free A4 give-out map in the same picture. This gets shown to me at the end so I know they’ve not cheated!
6. A higher score can be gathered, however, by spotting and photographing random and ridiculous items of my choosing along the way, so it's not just speed and navigation skills that get you points. See the list on the night. I will also give points for daft clothing and inappropriate tyre choice.
7. So you will need:-
a. As usual; bike, lights, helmet, drink, cycling equipment;
b. Map – Landranger 154 is good
c. Pen or pencil for writing on your map
d. Digital camera / camera phone capable of taking pictures in dwindling daylight
8. When you’re fed up/ tired / need beer, we all meet up at a pub and those who are late get points deducted! I then tot up all of the scores and work out who’s won.
9. There will be a 'Fantastical Prize' for the pair of riders with the highest score.

Golden Rules
 Stay safe and legal - this is a free, fun ride and the organiser accepts no liability – you ride at your own risk and are responsible for your conduct
 Wear a helmet at all times when riding and make sure that you have good lights
 All checkpoints can be visited via public right of way (walking on footpaths, of course!)
 Remember, you can bag each checkpoint only once
 Do not sabotage anyone else – cheats will be disqualified (IF found out AND we don’t think it’s funny)
 Follow the country code.

That's it for now. Have a good time plotting your checkpoints - most of them will be familiar. And see you all on Thursday night...there's no football on then after all .


Re: Pasty Tom's BIG Adventure - the Rules!

What time do we have to be at the pub (before points start being deducted ?)!

Re: Pasty Tom's BIG Adventure - the Rules!


It's a lenient 10 pm (about 2h 20 mins riding).

After that is considered severe showing off and you get points off for riding longer than anyone else.

Late penalties start small - 2 per minute for first 10 mins - then ratchet up. If you're more than 45 mins late (and that is LATE) you get a score of zero.

Full details of time penalties are on the give-out sheet on Thursday.


Re: Pasty Tom's BIG Adventure - the Rules!

ok, so if it looks as if we might be over 1 hour late, "for mechanical reasons - Ahem", can we phone ahead and book drinks at the bar before last orders and not get penalty points

Re: Pasty Tom's BIG Adventure - the Rules!

Hi Pat,

If you have a mechanical which will make you over 1 hour late, by all means phone ahead to put your drinks order in.

It won't get you out of the penalty points though...nice try!

If you have a mechanical early on, change your ride plan to make sure you finish on time or not too late.

Best regards


Re: Pasty Tom's BIG Adventure - the Rules!

Evening all,
Do you get bonus points for getting to the pub early?!?
I'll be out tomorrow evening, I have limited map reading skills & no GPS but have worked out the destination pub atleast (hopefully it's the six bells in Fulbourn!!) I'm pretty confident I wont be winning but I'm extreeemly confident I wont get docked point for arriving at the pub late.

Re: Pasty Tom's BIG Adventure - the Rules!

Hi Rob,

No bonus points for being early as such, but time becomes a factor if rider(s) are tied on their overall scores, i.e.earliest is higher placed on equal scores.

You got the pub stop right - it's the Six Bells at Fulbourn. (I hope they're open )

See you tomorrow - usual start point in Brookside.


Re: Pasty Tom's BIG Adventure - today is the day

Hi All,

Just checked the weather forecast and it looks good - it will be cloudy and mild this evening with the odd light shower in the early hours.

SO the maps and instructions are all printed out (there are 20 sets) and they will be in A4 plastic wallets to protect them just in case.

I'll probably park at Fulbourn and ride in - see you at 7:30 p.m. at Brookside.


Re: Pasty Tom's BIG Adventure - today is the day

So Pasty, how generous are you going to be with your points for 'daft clothing' ? Just wondering if I should go home and dig out some inappropriate tyres, or try and find a crazy outfit ??

Re: Pasty Tom's BIG Adventure - today is the day

Hi Katie,

They're each worth the same as some of the higher scoring checkpoints so definitely worth going for.

I suppose the downside of the inappropriate tyres is they could slow you down.

I thought that you always wore a crazy outfit?
