In short: Enough undulating hills to keep you guessing ! In full: Great race, very well organized, not a race for a PB , can get very challenging in the last 2 miles . Lots of undulating hills , beautiful countryside. Will definitely do it next year. Special one since it was my first half!
My advice to someone trying it would be to preserve your energy till 6.5 miles. Its hilly from around 3.5 to 6.5 mi. and please keep something for the last 2 miles, the gentle incline will kill you :)
