Holds and entries on the cheap!
Bicycle and chalk! Beginners - draw out the beacon and the hold. Now cycle to it. You can now see which way to join and how to take up the hold. Try from different directions. Advanced Users: Remove the patern of the hold and only leave the beacon. Doesn't take long but you do build up the picture of the hold in your head really quickly. But remember, you can't stop pedalling or you'll stall!
