I've just started running recently and have been building up very slowly because I have achilles tendon issues. I'm a 44 year old male, main sport is cycling so wanted to add another sport to help boost my fitness in general.
I'm currently doing 4.5km distances and hoping that my next run will be just over 5km!
I am monitoring my heart rate and I am finding this quite high - averaging 155 or so. Is this too high? Will I adapt and my heart rate start to drop eventually (as it has done with cycling) or is this too fast for my current state and should I reduce the pace - which is difficult as I am already running quite slowly - around 6.20/km?
Thoughts /advice welcome please.
