Old Listing (Archived - just for memory reference only)
When did Singapore hold the first Grand Prix ?
2008 ?
Try again ?
It was 1961 - the Grand Prix was held in the Thomson Road circuit. This 3 mile circuit covered the stretch of Old Upper Thomson Road from Sembawang Hills Circus to the other end where it met Upper Thomson Road and continued along this road until it reached Sembawang Hills Circus again. The Thomson Road circuit was reputed to be one of the most dangerous tracks in the world.
During the initial years, the main Motorcycle and Car Grand Prix lasted 60 laps, although this was eventually refined into two separate races - a preliminary 20 lap event followed by a 40 lap event. The first Singapore Grand Prix of 1961 was won by Ian Barnwell in an Aston Martin DB3S while the first Singapore Grand Prix of post independent Singapore (also run to Formula Libre rules) saw Lee Han Seng win in a Lotus 22 Lotus-Ford. The final victory went to Vern Schuppan in a March-Ford in 1973.
This multi-cache will bring you to tour along this old memory route :
WP1 : Circus Hairpin
- N 01° 22.717 E 103° 49.653 ;
- The lamp post across the road has a sum of the two red digits at 13 ;
- Find a glass bottle on a tree above the ground ;
- Note down the constructor name and the year in the glass bottle ;
- C1 = number of letters for the constructor name ; and
- Y1 = sum of the four digits for the year.
* if the physical cache is missing, use the web to find the "numbers" :
- famed as the only World Champion on both two and four wheels, John Surtees rode motorcycles and drove Formula One cars with equal skill and bravery.
- which year did he won the F1 Championship ? [Y1 = sum of the four digits for the year]
- which construtor's machine did John Surtees drove and won this championship ? [C1 = number of letters for the constructor name]
WP2 : The Snakes
- N 01° 22.738 E 103° 49.409 ;
- The lamp post nearest to GZ has a sum of the two red digits at 13 ; and
- P1 = number of the round rusty poles.
WP3 : Devil's Bend
- N 01° 22.803 E 103° 49.081 ;
- The lamp post nearest to GZ has a sum of the two red digits at 16 ;
- Find a label on a tree above the ground ;
- Note down the constructor name and the year on the label ;
- C2 = number of letters for the constructor name ; and
- Y2 = sum of the four digits for the year.
WP4 : Long Loop
- N 01° 23.206 E 103° 49.090 ;
- The lamp post nearest to GZ has a sum of the three red digits at 8 ;
- Find a glass bottle at the tree base ;
- Note down the constructor name and the year in the glass bottle ;
- C3 = number of letters for the constructor name ; and
- Y3 = sum of the four digits for the year.
WP5 : Peak Bend
- N 01° 23.271 E 103° 49.037 ;
- The lamp post across the road has a sum of the three red digits at 10 ; and
- P2 = number of the round rusty poles.
WP6 : Range Hairpin
- N 01° 23.395 E 103° 49.066 ;
- Count the colored segment of the tall red+white structure ;
- R = number of red segments ; and
- W = number of white segments .
Substitute the numbers into the following formulae to find the "formulae" waypoint cache which is a granite rock :
- N 01° [Y1+P1] . [W] [Y3/W] [R-W]
- E 103° [C1+C2+C3+4+Y2] . [(P2X40)+11]
Upon arrival at the "formulae" waypoint, look for a granite rock which has 2 sets of 3-digit written on it.
Punch the 3-digits into your GPS and final cache is within tens of meters.
Most of the findings should be bash-free; if you find yourself somewhere else, then you have gone too far in.
Beware of animals in this area and conduct this caching in bright day light.
After SL, please hide the "tool" (to open the cache container's cover) under the cache.
Enjoy the caching !
Optional : bring along a flat-blade screwdriver in case the attached tool is missing.
