Chasing States... Challenges, Choices and Chuckles and what is a "Back to Back" anyway? Funny story, my colleague is from Mexico. She's not a runner, but her uncle recently qualified for Boston and he posted on one of his social media accounts about his "PR." She knew I had run Chicago and Berlin and so had he. I asked her about his regimen, training and suggested, jokingly that he coach me (because he is many miles away). I later inquired about his PR and she chuckled. She told me the first time she saw it she thought it meant for "Puerto Rico." I said but he's from Mexico. She said I know, but I couldn't figure out why else he would post PR! (runner peeps now you know that tickled me)šš. She was so serious too. This reminded me how we can have a complete conversation using jargon that keeps so many out of the loops. Although it is unintentional it tends to isolate others from the conversation and the sport. With that being said...
