Hi Michelle, hope all goes well for your husband. Going on previous years, as race day gets closer and people pick up injuries or realise what they've committed to, more places become available. So would suggest your husband keeps the training going and you keep your eyes on the forums or even start a new thread yourself.
Phil, I think Bath is sold out anyway. Have tentatively pencilled in the Tewkesbury Half on 19 May. Not too far from your neck of the woods. It is however the day after my daughter's birthday so will need to see if anything's already planned for the weekend.
Also, I know you said no more marathons.... But Loch Ness is such a great race. Seriously thinking about this now.
Paris is 8 weeks away. Managed to get in 5 runs this week, 43 miles ending with 16 yesterday with the second 8 at marathon pace. Training's going better than 2 years ago, touch wood. Hopefully I can look for another sub-4.
