The runner who wants to change the registration from one race to the other has to contact us through the email address info @ bcntrailraces . com or by using the form here (+).
When changing from the GTC to the GTCX2 (relay race), the data of the other runner has to be submitted. The cost will be the difference of the cost of the inscriptions on each race.
When changing from GTCX2 (relay race) to GTC there will be no refund of money and only one of the two runner previously registered can make the change.
These changes can be requested until November 10th included.
