Grid References and Direction

•
•
Eastings and Northings
(E comes before N) “Along the corridor and up
the stairs”
You must give SIX FIGURE references for
checkpoints and know where you are by grid
reference at all times !! (Compass roamer)
Going from north to south, what the 6figure grid references for the 4 circled
points ?
What direction are you travelling from
1 2  3 4 ?
At this stage you only
need vague directions of
the 8 cardinal/
intercardnal points but
16 is better !!

• Numbers on contour lines show height above sea level (how you know if its up
or down)

Top tips for speedy route card production
1. Write your group number and day
number (1 or 2), day (Sat or Sun) and
date (eg. 25/4/15) in the top right box.
2. Write in the start location and grid
reference in the top box
3. Split the route into sections (legs)
4. Write in the end of each Legs
destination and grid reference
5. Write the direction travelled for each
leg in the next columns (eg. NW)
6. Use string to measure the distance and
write that in for each leg (eg. 2.5)
7. Work out the time it will take for each
leg (20 mins per kilometre, so 50 for
2.5km)
8. Write a written description of the legs.
9. Total up the distances and times (in
minutes)
10. Enter the start time and work out the
finish time – write that in too!
