I've done the Birghton Half before, but went back this year as it was their 30th anniversary. The course is mainly along the seafront with the little out and back around the Old Steine. The Brighton crowd support is always really good. The general organisation was really good and the marshalls and volunteers did a fantastic job despite the weather. Bag drop was available but I didn't use it as my hotel was close to the start/finish. The water stations were well stocked. The medal was specifically shapedas a "3-0" to celebrate their anniversary.
It is a really good event and I would recommend it to everyone.
