Bundle up the TCC Race Prediction Calculator and MAS Determination Spreadsheets, two of TCC’s most innovative and popular resources to save you money, time and stress.

The Bundle includes THREE expertly devised race prediction calculators:

1. MAS RACE PREDICTION CALCULATOR – Excel based calculator comparing VDOT to the TCC MAS Model
2. MAS RACE ENGINE – Interactive HTML calculator & slider comparing VDOT to the TCC MAS Model
3. MAS DETERMINATION SPREADSHEETS – Excel based spreadsheet that enables coaches to accurately determine MAS for five of the most commonly used field based aerobic fitness tests. 

RACE PREDICTION CALCULATOR UNPACKED

The MAS Race Prediction Calculator and the MAS Race Engine uses your Maximal Aerobic Speed (MAS) to generate accurate, physiologically-grounded race predictions for 2km, 5km, 10km, half marathon, and marathon. Built on Jack Daniels’ VDOT framework and TCC’s proprietary MAS model.

Two prediction models are displayed side by side – 1) the internationally recognised Daniels VDOT model and 2) the TCC MAS Model, which applies research-validated MAS percentages developed through years of coaching practice. This allows you to compare both, whilst acknowledging that the practical application of the Daniel’s VDOT predictions can be too aggressive and fast for athletes and runners alike. Trust the data and make smarter race prediction decisions.

The calculator is an interactive HTML tool — no app download, no subscription, no internet connection required. Open it in any browser, enter a MAS value, and the predictions update in real time as you adjust the slider.

The MAS determination spreadsheets will save you an incredible amount of time, stress, and frustration as you won’t have to worry about ruining your conditioning prescription by using erroneous MAS values. The Maximal Aerobic Speed determination spreadsheets will ensure that your conditioning prescription is incredibly accurate and physiologically effective, especially if used in conjunction with the TCC Conditioning Education Bundle.

These tests included in the spreadsheet are:

1. Beep Test (20m Shuttle Run)
2. YOYO Intermittent Recovery Test – Level 1
3. Time Trial (varied distances)
4. Bronco Test (1.2km Shuttle Run)
5. Maximal Aerobic Speed Test
