I've combined a 50, 39 & 26 Crankset with the 10 speed Tiagra 12-30 cassette. The 26t small chainring and 30t rear cog combination can crawl up a 20% slope at 2.7 mph with a 40 rpm cadence.

The practical chain-wrap capacity, with a correct length chain, of the road "GS" RD allows the big-big combination of 50t front Chainring & 30t rear cog with a little safety margin and also allows the small-small combination of 26t & 12t without any slack in the chain.
