A full lap of Jeju Island following the well marked and serviced Jeju Olle Trail. A perfect FKT route which I was surprised not to find on your website. The blue-line 210km route around the island regularly sees fast attempts by Korean runners but this route offers a significantly better trail (maintained by Jeju Olle), 4000m more elevation gain and a much harder challenge.

A Vosges classic from the Col de la Schlucht to the Hohneck (1,363 m), one of the most beautiful summits of the Vosges and the third-highest after the Grand Ballon and the Storkenkopf. The route climbs through beech forest past the Martinswand cliffs to the summit plateau, with views over the Hautes-Vosges and on clear days to the Black Forest and the Alps. It then drops past the Lac de Schiessrothried into the Frankenthal, a classic Vosges valley, and returns along the Krappenfels cliffs to the pass.
