Completed W6 R2 last Thursday and the intervals were really getting to me, I was just looking forward to stopping so much! I had planned to do R3 on Saturday, really wasn't looking forward to it at all - just negative thoughts. However I ended up having 3 rest days - I went to see Prince on Friday night and with all the dancing, eating, drinking and generally living it up, I just wasn't in a fit state on Saturday at all!
It was brilliant tho and well worth it as on Monday I went for it and actually quite enjoyed the full 25 min run! Thank God for Pete Tong again, but after the first 5 mins or so I got into a good rhythm. I took all the advice and slowed down to 7.5 kph then upped it again for the last minute to 8.5kph as per Laura's suggestion. Think I ran about 4k all in. The extra 5 mins was tiring but well pleased with myself! Thanks everyone on here for your suggestions and advice, I really didn't think I'd be able to do this!
