I adore open water swimming. I'm very fortunate to have a local lake that's available most days of the week and is free to swim in. I'm hoping to keep it going as long as I can into the colder weather - I'm not looking forwards to pool swimming over the winter!
A sub 1hr 3.8km swim would be great, and might be achievable based on current training. I need to sort out my wetsuit so it stops trying to behead me mid-swim though, that's most distracting and definitely not compatible with improved times!
A sub 25 minute 5km run might be doable, but I think I'd probably vomit at the end!
A sub-5hr marathon is definitely achievable if I can stop faffing about at feed stations. I'm too tempted by crisps, that's my problem
