Michaela Kiersch leads the current 12-month female combined ranking

Over the last 12 months, Michaela Kiersch has sent two 8B+ boulders and one 9a route. There might be some unreported ascents out there from other female climbers, but as it stands Michaela is currently the only female having done such top-level grades in both disciplines. In the all-time combined list, there are likely only four female climbers that have done at least one 8B+ and a 9a; Janja Garnbret, Ashima Shiraishi, Josune Bereziartu and Mélissa Le Neve make up that list. There are at least another ten women who have done 8B and 9a or 8B+ and 8c+.
Female climbers have greatly narrowed the performance gap when it comes to bouldering and sport climbing, but interestingly there's significantly fewer female climbers combining both high end sport climbing and bouldering. (c) Nina Williams
