OK, it's just words when you understand them but some of the words become jargon in the mouths of others and it's easy to lose track of what they mean. Running is as guilty of this as any so I wonder if anyone could run through the use of some of the following:
Splits - clearly a way of noting what speed you are doing at a given point but what is their significance and how can knowing this help?
Cadence - presumably not a musical term.
Pace - the difference between this and cadence.
Speed - probably obvious but, when combined/compared with the above, possibly not.
I'm sure there are others that peolpe will be wondering about.
Or maybe it's just me.
