Why does it need liPo? All you need to do is have a pit stop to change batteries in the middle. Makes it more interesting in a 20 minute race, do you go for gearing for 10 minutes with one pitstop or gear for less runtime and two pitstops.
After all they used to run 30 minute finals in US oval racing in the late 80s with 1400mah batteries. For a one off event it is unlikely anyone will build a quick change battery system.
