That's better!

I just had my best ever mile reps session:

Lap	Time	ave HR
1	7:36	139
2	7:31	142
3	7:28	146

Now here's the thing: I set out to do the reps at 5km pace as suggested in a marathon schedule I got from the Pfitzinger/Douglas 'Advanced Marathoning' book. I reckon I could do a full 5km at 7:28/mile, particularly as I was still easily aerobic and well below my 155bpm lactate threshold. On the assumption that this is indeed my 5km pace, then that makes a 5km time of 23:12. Feeding that into the Runner's World calculator gives a marathon time of:

3:42

OK, that may be stretching it a bit, but I'll take any form of positive reinforcement at the moment. Bring it on!
