What accent is this?

There's two commentators, the second starts to speak at 0:22, then you can hear both.

Both Australian? Or what? If it's Australian, is that kind of Australian so different from British RP-like accents? It doesn't seem very different to me.

The second (0:22) guy appears to speak RP. The first one sounds RP with Scottish(?) influences (occasional hard R). If they are Australian, they sure don't sound like it.

I only thought of Australian English because that race was in Australia. I really have no idea what accent it could be, although it sounds like a kind of RP to me.

first one doesnt sound aussi at all. RP sounds close.

second not aussi either... kinda west county to me, though ive a bad ear for uk accents

Apparently they're both from Merseyside, though I'd not have guessed it. The first sounds significantly more northern than the second.

They're definitely English accents. Not Scorttish, and not Australian. One has some slgihtly northern vowels occasionally ("oo" vowel in much"). If they're from Merseyside, they've lost their Scouse accents to the point of it being unidentifiable. Perhaps that's where the remnant trilled R comes from, but a trilled R is not unique to Merseyside in English accents: check 1950's RP and you'll hear a trilled R as standard.

I suppose an artificial RP is still practiced by some television commentators, unfortunately. On of my former college friends is now a radio sports commentator, and hearing his radio voice in place of his normal light Leicestershire lilt is truly cringeworthy.
