Decided to run a race this Sunday - a half marathon - my first since July and a good test of how my knee injury is holding up. A bit of a train through race as I will probably only take one easy day beforehand.
Last outing was over 20k and I aimed to run at an HR of 173-177(around 85-88% of max using the Karhoven method). I feel I can push a bit harder and will aim for 175-180 (175 for the first half). Although I think the course is quite hilly I'm confident that a PB is possible (best so far this year of 1:35).
Any of you using your HRM for races? What does it tell you? And more importantly what colour shorts should I wear?
