The thing I will need to work on most is the bike. But realistically I won't be able to do many sessions per week. So I will probably arrive on the start line undertrained, which has been my MO for the last few years anyway.
If there is alcohol in the drinking challenge then I will also have to practice a bit as I hardly drink at all these days. Now that sounds better.
Everything is on hold until after May in any case due to work and other things.
