First Marathon - target heart rate?
Hi All - I'm doing my first marathon in Barcelona in early March and am a bit nervous. I'm using this race as a target for getting a good base of training in for the summer so I don't have a target finish time, I just want to finish feeling relatively ok and pyschologically get a marathon 'under my belt' in preparation for going long (eventually). So rather than picking a race pace I want to stick to a target heart rate instead. Got some advice on this forum recently on using heart rate and RPE and now have a rough idea of my pace at different heart rates and the RPE for each, but obviously fine tuning and I was thinking of trying to maintain my heart rate at mid Zone 3 for the marathon(an experienced marathon runner told me the pain should be like a 'nagging toothache', so I think that matches with around there!) . Anybody with experience of a marathon or an IM who's done this who can steer me on this? Too high or too low?
