Hi Postlady. I know the bikes you're talking about and they look a beast to ride. I think a lot of people also don't realise how much ground our posties cover on their rounds. Like Hebe said, thanks for the great work that you do.

I don't like cycling shorts so I wear padded underwear under tights or whatever. There are a couple that come in size 18 here: http://www.wiggle.co.uk/?s=ladies+undershorts. I use this brand and find it comfortable. Endura is another brand that you may want to try.

Finally, is it worth having a word with your union rep - either the workplace or health and safety rep? These are the sorts of issues they should be raising on your behalf.

Good luck.
