Second Instruction a child has to follow before running race (6)
I believe the answer is:
steady
'running race' is the definition.
'steady' can be an answer for 'running' (thesaurus). I'm not sure about the 'race' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for steady that I've seen before include "Secure" , "On an even keel" , "not easily shaken" , "Not faltering" , "Stable, not shaky" .)
