Spikes or no spikes

Well, the conversation has been all about whether or not to wear spikes for the run. In the city, the pavement is treacherous and you need spikes. But a guy in the running shop said the course has loads of sand and we don't need them. At least not if I am only running for a time of 1.35. Still not sure and we start in 2 hours. I will do a couple of test runs before I leave the hotel. Then I will just have to trust to luck. Midday has lots of light but it is already getting dark. It feels like early evening and I have just finished lunch. Picked up number this morning alongside many others. Very excited!
