The above link contains 4 x HITT Running workout sessions to get moving fast. Some of it is very similar to work you’ve already done. The duration of the sessions vary from 15 – 75 minutes.
They all include a warm up run before moving onto the task itself. The Hill session is particular interesting as it’s a good way to tackle hills! Don’t forget to include some dynamic stretches too.

This page also has a link to dynamic warm up stretches which are worth having a look at
Examples of Dynamic stretches include:-
Knee hug – lifting knee up into the chest – you can either do this as you walk or on the spot
Side lunge
Straight leg swing
Frankenstein kicks – arms out straight – kick one leg up as high as you can towards outstretched arms. Drop leg back down and kick up opposite leg.
