I would be shocked, pleasantly, but still shocked, if Hill get's the B standard. He was a 13:25 runner last year, but he's lost significant time to injuries. So I'm not sure his 5k fitness is even as good as last year.
That said, the field looks like it's might be relatively good for Hill. There's only a handfull of sub 13:20 guys and only 1 (I think) sub 13:10 guy. So the pace might well be in the 13:15 to 13:25 range. However, in my opinion the closer to 13:15 (or fast) the pace is the worse his chances become.
I think the only way True will think about Hill is if both get caught off the main pack running together. In that situation I think True will make Hill lead, or if he leads, he'll slow down.
Hill certainly has the talent to be a sub 13:20 one day. It's just a question if this is the year for him.
