It seems that slightly "unique" hearts are quite common amongst us runners .... I've had all the tests under the sun and have quite an irregular heart beat - take a modest dose of beta blockers to calm it slightly and have been offered ablation to try and esentially burn the rogue cells that are misfiring and causing the irregularities or so they say. My running hasn't been affected as far as I can tell but my heart rate range has changed due to the beta blockers - max is now around 160 and resting around 40-45. Definitely worth getting all the tests done, as they should beable to offer the best solution unique to your case. Many people have irregularities and they don't even notice. Me being a skinny bugger means you can feel every skipped beat etc which can be a little annoying at times but have learnt to largely ignore it. Not easy sometimes tho'!
Good stuff Heather - going to try incorporating a session that is flexibility specific this campaign - ie 3 mile warm up and an hour of stretching..... the top physios are recommending this! How many runners actually do this? Maybe 1%?
Swimming a few times a week is helping to keep things balanced and the core stronger too I think. Training will become more run specific in the new year. Aiming to hover around the 30 miles a week mark up until then.
