A cracking half marathon PB!... or not?

14M - incl Cardiff Half Marathon in 68.26 (14th; 5.13min/M)*
*hmm... I hear now that the course may have been 150-200m short, meaning I might have snuck under 69, but I shouldn't count this as my PB. Grr.

I am dead chuffed with this [whether or not it was short]. I was pretty up for the race - and had my cousins camped at 5 miles to speed me up too. It's a healthy 3 minutes faster than the PB I set a month ago in Greenwich and 5 and a half faster than my previous best. Psychologically, it's great to be getting close to 5 minute miles. I set off at 5.10min/M and was on my own in about 12th until a group swallowed me at 6 miles. I then stuck with them and kept pretty even pace with a few surges to the end. I'll be stiff tomorrow - the last 3 miles were HARD.

The time [if it counts] gives me entry to the elite section of the Great South Run next weekend (if there's time). It's an IAAF Ranked 10 mile race and should be fast. It'd be nice to get close to 50 minutes if my legs are ready. I went through 10 in 52min20ish today.
