is the extended handle tube straight? Mine looks curved.

It is supposed to be straight I believe. The handle pieces have to slide into each other to collapse it down; the handle has to relatively straight to do that.

will it measure over grass?

Yes, it will measure over grass just take your time. Thanks

Can be used to measure 5K and 10K race lengths?

5K and 10K races are actually 5K and 10K meters. The Roadrunner measures in feet and inches. The unit is small and is made for shorter distances. The small wheel and mechanics inside would have to endure a phenomenal beating. I would think that to measure such great distances your would want a unit made for highway measurements such as the Keson RR318N (10,000ft) or the Keson MP401E (100,000ft).

will it measure over grass?

Remember that any measurement over uneven bumpy terrain will add length to it. If the ground is level, grass will have only a small effect on measurement. If you want terrain measurement and not straight line level measure then it's ok.
