# 10x10 cm obstacle

To qualify for IUF level 3 you have - among demonstrating other skills - to ride
over a 10x10 cm obstacle. It is not mentioned in the skill levels’ list, what’s
the height of this obstacle. Are there any definite standards for that? Of
course there are, but I couldn’t find them. So please let me know, what height
is usually used.

The obstacle is 10x10 cm with an indeterminate length. So, the obstacle has a
height of 10cm, with a width of 10cm. A good source for this obstacle is a
lumber yard, where you usually can get them to cut you the proper size obstacle.

Getting over the obstacle is up to you: You can ride over it, hop over it, or
whatever (as long as you remain on your unicycle ).

For those who are just starting to learn going over obstacles, I usually
recommend starting with something a lot smaller, then working your way up to the
obstacle of 10x10 cm.

The height is 10cm. The depth (distance from front of obstacle to back of
obstacle) is also 10cm. The dimension missing from the definition is the width -
this can presumably be anything from the width of your tyre (or slightly less)
to infinite.

The idea being to demonstrate that you can go up a bump and, almost immediately,
ride back down a bump. “Bump” here being used as a technical reference to a 10cm
height difference.

time it’s been raised on this list (and/or newsgroup). Maybe the powers that be
could tidy up the description in the skills list…
