Hola from sunny Spain!
This is for for anyone struggling at the moment or even those who are thinking of starting or perhaps quitting (DON'T GIVE UP! NEVER EVER GIVE UP!).
Maybe you're struggling to finish some of the runs, maybe you're out of breath, maybe you're lacking confidence in yourself, 'fearing' that 3, 5, 8, 20 or 25 mins is out of reach or 'impossible'. Have NO FEAR... for this will help you. DiscoRunner has promoted this video lot previously and I've been posting it a lot recently too.

and also this: the Running Shuffle (a little quicker but shows a useful technique)

SUMMARY: you CAN do it, but you need to find the right pace for you. Keep it SLOW. Go at the right pace and at the end of the final running bit of every session, you *should* feel like you could carry on.
Think 'JOG'... not 'RUN'.
Good luck!
