$45 is still a good price.
I did the Bolder Boulder 10k in May. $70. But I had to be in Boulder that day anyway and it was only about 50,000 people. The finish was into the University of Colorado Boulder football stadium. The stands were at least half full with fans cheering you in and your face up on the Jumbotron. Very cool.
I will be running Coll Half Marathon on the Isle of Isle of Coll in £15.
