From what I have seen of bryony frost, which is very little, I would imagine that what she thinks is resentment towards her for winning big races, is actually just weariness of her, as I may be wrong but I imagine if I had to spend any sort of long period of time around her I would be clawing at the exit door.
hollie doyle, rachael blackmore and hayley turner have also been successful and won big races but I havent heard about much in the way of resentment towards them, as unlike bryony, neither of them come across as incredibly annoying :glee:
