Note: The recommended running machine solution for speedtraining is the h/p/cosmos pulsar 3p or bigger. 

Consider the normal physical performance limitations of single phase voltage power supply 230 Volt / 15 Ampere. During special high performance applications ("jump-on", lateral running, "360s", etc.) and with heavy subjects there may be performance limitations with the single phase voltage power supply. 

For high performance applications a 3-phase voltage power supply and a h/p/cosmos running machine with a higher performance drive system is highly recommended. for example h/p/cosmos pulsar 3p, venus, saturn. For speed & sprint training safety arch is an obligatory requirement.
