15W - the weather has picked up a fair bit in the UK. I can't speak for Manchester, but in my area the flooding has receded significantly (for the time being).
Go Caz / Mennania - Julian Goater is a big proponent of hill sprints to build strength and prevent injury in his book "The art of running faster". I'm wary of starting them during marathon training, because I believe that I'd be more likely to get an injury while increasing mileage at the same time. I do intend to do some hilly sessions, though. Most likely during a midweek GA or MLR.
NN - thanks for clarifying, and good luck with the HM.
YP - I've pm'd you 
Finished the fourth week with 15m MLR this morning. I felt a little like I was flagging at 8m, so I took my gel and soon felt like speeding up. I was held up towards the end by some horses blocking a narrow path. Admittedly it was a bridal path
Pacing went pretty well. My pace range for MLR is 10:48 to 9:54, and HR range 141 to 160bpm. My heart rate peaked at 157bpm (avg. 140bpm) and the splits were:
10:34/10:46/10:44/11:00/10:53 (included a pit-stop
)
10:26/10:09/10:12/10:09/10:00
9:53/9:53/9:56/9:51/9:38
I've enjoyed all of the training so far and have found it "comfortably hard", but next weeks training scares me! Starting off with the 9m/5m LT session, and finishing with 16m including 10m @ MP
Eek! I'm going to be dreaming about the following recovery week.
P.S. I have a protein shake for a recovery drink. I don't know if it really helps, but I enjoy it nonetheless
