Watts per Kilogram: Using the CompuTrainer Indoor Ergometer to Improve Your Performance
by Richard Wharton. This e-book contains over 125 pages dedicated to understanding just how powerful you can become with a CompuTrainer as part of your program. The ultimate companion to ERG+, CRS+ and Real3D.

Main View
The Real3D's main view is the top view of your course, and the bottom window shows the elevation view. As you pick and pull on points in your top view, the impact to the elevation view is shown. Grade and distance changes are computed as you edit. When you insert and delete road sections, the elevation/grade operations are automatically performed. Best of all, you can edit roads ANYWHERE on your course at any time, without deleting all of the sections before your editing point, like the CompuTrainer 3D course builder requires you to do. |

Elevation Data and GPS
In general, the GPS tracks you record may not be precisely what you want in a bike ride. Most people take time to linger and chat at some point in an outing, ride in circles at stop lights, or they answer the call of nature, without remembering to turn off and on their GPS track recorder. These behaviors introduce wandering, compact loops or wiggles in the track data. Still others go hiking, perhaps rock climbing, and want a bike ride made from the route, forgetting that it involved a few perfect vertical transitions, staircases etc., which can't be recreated on the CompuTrainer, of course. We use signal processing techniques to eliminate discontinuities and undesirable "lingering" sections, and you can even control the level of detail used in performing some of these operations.
Most GPS units' elevation data is usually pretty inaccurate, or "noisy". Small inaccuracies in altitude can lead to some pretty poor, choppy recreations of the ride. We provide an elevation smoother that uses signal processing to remove the measurement noise from your altitude data. The diagram below compares the real GPS altimeter data to the smoothed data. You can also edit the profile segment by segment, without having to delete all of your course up to that point, like the CompuTrainer course building tools do. You save your work to an .xyz file so you can edit the data another time. Real3D never overwrites your original GPS data files.

Fixes CompuTrainer Minimum Turn Radius
The CompuTrainer 3dc road format enforces a minimum turn radius, and often GPS data is collected that would require turns less than that minimum, especially when mountain biking or doing time trial turnarounds. We let you control the maximum turn radius and other parameters to "tune" the smoothness of your course. If there are still places where the minimum turn radius cannot be satisfied, a "lollipop turnaround" is inserted automatically, like a real life time-trial turnaround point. Below is shown a case where the lollipop is inserted.

Out and Back Courses
Since the CompuTrainer 3D display will flicker on out-and-back courses, due to small differences in elevation data, we provide you with the tools to separate the overlapping roadways into two separate, parallel roadways which doesn't affect your ride distance, grade, or experience, ...except that it eliminates the flickering! Below is a before and after screenshot of a "repaired" out and back course. |
