UMAG, Croatia, BARCELONA, Spain– This weekend, over 2,560 trail runners will take to the Istrian peninsula of Croatia to race in the 11th edition of Istria 100 by UTMB. Among them will be over 50 elite runners who will be looking to secure their spot to the UTMB World Series Finals in Mont-Blanc.



All eyes will be on Spaniard, Pau Capell (UTMB index: 890), who comes hot off a 7th place position at Chianti Ultra Trail by UTMB two weeks ago. Racing the 110k, Capell will be hoping to grab his golden ticket to the UTMB World Series Finals. Also racing in the 110k will be Janosch Kowalczyk (DEU, UTMB index: 875) who won the same distance at mozart 100 by UTMB last year, as well as fellow Spaniard Pablo Villa who unfortunately DNF’ed in the Miler at Doi Inthanon in December.

Racing the 168km (100M) will be Esther Fellhofer (UTMB index: 716) whose most recent results saw her take the win at KAT100 by UTMB, as well as coming second at Julian Alps Trail Run by UTMB last year. She will likely be challenged by French trail icon, Claire Bannwarth (UTMB index 708) who made headlines when she won the Winter Spine Race in January.
