no overlap on course but the old st johns ambulance are going to have there work cut out.
that 10k (I did the first and never again) has a large turn out.
part of the bike course may go near the 10k course- maybe they want to double up on marshalls!
Just make sure you get the right t- shirt and medal when you cross the finishing line.
Your mates wont be impressed with a sub 2 1/2 hours for a 10k run!
