Well, I did it! W5R3, the 20 minutes... wasn't as hard as I expected, but still not easy! I'm running about 8.30 mins per KM, happy with that as it's pretty hilly around here. Pleased with myself, I woke up coughing a bit with a runny nose, think I might be starting a cold... if so I'll have a few days off, but just wanted to get this run out of the way! And I've done it!
Looking forward to week 6...
