The new iClass Builder Player creates a way for Instructors of Indoor Cycling or Spinning® classes to use their iPod, iPhone or iPad to deliver master instructor level classes on their iOS mobile devices. Everything from simple target intensity levels in RPE (Rate of Perceived Exertion) to advanced training with Heart Zones®, Cadence and Power can be built into every class with iClass Builder and delivered with this Player app. Cues for changing position can be precisely timed to the music, changes in RPM can be fined tuned, and classes can be continuously improved. Music sources include Spotify, Apple & Dropbox. For instructors lucky enough to teach in a room with a projector or flat screen TV, iClass Builder Player will also project the ride profile along with your personal selection of additional info. On top of the profile, you can choose RPE, Heart Zone, RPM, Power, Track Name, Artist Name, Album Art, Segment Title or even your detailed cues. This next generation of the app also provides a way for instructors to share classes, a long requested feature, and also buy classes; making it especially easy for new instructors to get started. For the more experienced and master instructors, there are also features to allow you to sell your classes – to finally get at little something more back from all that hard work. iClass Builder Player is also loaded with tons of extras like an on-demand interval timer, instant album and artist info at the tap of a finger, and all of your pre-determined cues in an immediate access scrolling screen for easy in-class review when you need it.

Empowering the ultra-running community with a resource to enhance the experience and help to make dreams become reality. At Ultra Crew Hub our goal is to provide our community, through each of our own experiences, the information that are experienced during these events. We want to be a place where we all can give each other a peace of mind, a breath of fresh air, before and during these events. It is what our community is all about. We all have very different struggles, some of you have to do this all alone, and that can be very intimidating- sometimes feeling alone and left to figure out the next move. Some of us have crewed solo, and know that feeling of the gun going off, your runner leaves and your left scurrying to get to the next aid station before your runner does- even though you have a few hours to get there.
