Evan and Erin met on the dating app "Tinder". It's really nothing special. What is special is that they happened to be within each other's radius while using the app at the same time (they each lived outside the other's radius at the time). Out of all the matches, they were the only people each of them ever met off the app (he sealed the deal with the offer of burritos and margaritas at her favorite restaurant), and they both subsequently deleted it.
After competing in the Obstacle Course Racing World Championships in the UK, the couple took a short vacation in London. The ring was burning a hole in Evan's pocket the entire time. Knowing Erin's detest for crowd's and cliches, he found the perfect private moment in their Knotting Hill flat on the morning of their last full (and most relaxing) day following a trip to Portobello Market for croissants and a walk around their neighborhood.
