I've just completed W3R3 - and man, it feels good! I'll admit after W3R2, I was convinced I couldn't do it - bad weather, slightly different route (due to the weather), breaking in new trainers and a really dodgy toe nail - all added up to me not running the full 3 minutes on either repetition but tonight it was completely different. Thanks to the advice on here, I dropped my pace for the 3 minute section so whilst I've not gone as far distance wise, I've managed to run for 3 minutes straight. Twice!!!
I also think I've caught a bug - the running bug - I've been itching to get my trainers on all day at work and I'm so glad I have done! Can't decide whether to repeat the run again (to check tonight isn't a fluke!) or to bite the bullet and go for W4R1 on Thursday...
sorry for rambling, I'm just had to share!
