| アメリカ50州マラソン制覇は、私の師匠であるKumaちゃんに教えてもらった。50
States Marathon Clubというクラブがあって、10州を越えると入会できるそうだ（入会済）。この広いアメリカ全土を走りきるなんて、夢のような話ではあるが、飛行機・車で旅行してしまいがちな広大な大地を、自分の足で踏みしめることは、またある種の価値があると思う。 下の地図は私のマラソン完走地図を示している。ちなみにマラソンが2州にまたがる場合には、どちらかかでカウントするルールだ。赤色はマラソン完走を示している。2周目は黄色で示している。また、地図にカーソルをクリックすると、それぞれの州の主なマラソン大会にリンクするようになっています（工事中）。
