Calculate in km the distance cycled in Vineyard Race, Ocean to Ocean Race, and Karoo Fun Race.

Distance = $70 \text{ miles}$
Conversion: $1 \text{ km} = 0.6214 \text{ miles}$

The distance cycled in Vineyard Race is $\boxed{\text{112.65 km}}$.

Distance = $130 000 \text{ yards}$
Conversion: $1 \text{ yard} = 0.9144 \text{ metres}$ and $1 \text{ km} = 1000 \text{ metres}$

The distance cycled in Ocean to Ocean Race is $\boxed{\text{118.87 km}}$.

Distance = $888 500 \text{ feet}$
Conversion: $1 \text{ m} = 3.281 \text{ feet}$ and $1 \text{ km} = 1000 \text{ metres}$

The distance cycled in Karoo Fun Race is $\boxed{\text{270.80 km}}$.

Distance = $5 832 154 \text{ inches}$
Conversion: $1 \text{ inch} = 2.54 \text{ cm}$, $1 \text{ m} = 100 \text{ cm}$, and $1 \text{ km} = 1000 \text{ m}$

The distance cycled in Charity Fun Sprint is $\boxed{\text{148.19 km}}$.

Total distance = Distance (Vineyard) + Distance (Ocean-to-Ocean) + Distance (Karoo) + Distance (Charity)

Required distance = $600 \text{ km}$
Since $650.51 \text{ km} > 600 \text{ km}$, Jappie has cycled more than the required distance.
Therefore, Jappie will be able to win the club cycling cup.
