You are going to need to be much more than a runner and hiker to climb Whitney in February. You don't "hike" Whitney in winter. If you have to post here looking for a group to train with, it is a sign you aren't equipped in snow mountaineering and team winter travel; both of which are essential for winter Whitney ascents. I would recommend reaching out to professional guiding company if you really want to climb in February. Otherwise, wait until June at the earliest.
