It was great, fantastic atmosphere. Completed in 44 mins and 45 secs which I was well chuffed with, as my previous 5k took 51 minutes - so a new PB.
The weather was bearable - cloudy, so not as warm as its been lately. But, I found out I cannot run very well on grass (more used to a hard surface). Luckily, after the first 1k the running surface was tarmac.
We were assured that the run would be pretty much level - they lied! There was this big-assed hill, went on for ever (so obviously not very steep) - all the same damned hard work.
It was a great experience and we are looking forward to doing another one (or a 10k) next year.
