Be Prepared
Two days before the race pack your bag with whatever you usually eat and drink before, during and after the race. Get all the kit you are going to wear in one place and make sure you have everything.
Get There EarlyMake an effort to speak to your fellow runners, especially ones that have done the race before. I have never come across a runner who isn't willing to share his/her tips that they have picked up. Also talking and joking will calm your nerves.
Remember you are not the only person racing for the first time, their are a lot of other people feeling just as nervous as you. Once the gun goes off and you are on your way all that tension will disappear, get into your stride and enjoy.
PS. No matter how many races you do, you will always get to the line with a certain amount of nervous tension, but that's what makes racing exciting.brilliant-running-tips.com
