Manila Runners, half marathons

Did anyone take part in the Sofitel Half Marathon last weekend? I've only just recovered! Now Im looking at the flyer advertising the event next month, the Caliraya Protected content Laguna...
Since it will involve finding accommodation in Caliraya on the night before the event, it may be cheaper to share with some fellow runners.
At present Im undecided, but if theres a group of us Im more likely to go.
Any interest?
