I’ve entered it, hadn’t even seen the start time tbh, might mean I can drive there on the morning instead. I was swayed by: cost, timing between Slateman and IM Wales, and Snowman not running in 2026, as far as I understand. Not looked at the route though, I’m sure it’ll be ok.

If you mean the steelman it usually starts about 10am unless they change it, can register on the morning and small transition.

Camping as well if you’re mad :joy:

I’m sure I heard or read last week that Wales would be the only UK “official” full IM event next year. I wish I could remember where I heard it otherwise I’m just spreading rumours. Which it seems I am.

I don’t think I’d be shocked if Leeds doesn’t happen.

Was considering roadford lake half, anyone been there?

90

Yeah did it a couple of years back as did @buzz. Really enjoyed it. Quite low key but nice feel still.

Nice easy lake swim. Bike is a 2 x lap affair. Really nice course actually. A couple of punchy little climbs, but much quicker and more rolling than I expected around the moors. Traffic was pretty quiet too.

Run was mixed terrain and not my favourite run course ever. But it was varied, reasonably hilly for a tri but nothing silly. 4 x laps if I recall.

Overall I’d still do it again - reasonably priced and less than an hr away from me helps!

I did somersault over the handlebars into a ditch on the bike coming in towards the end of the last lap. Though I don’t think I can blame the course for that!! :rofl:

Thanks @gingerbongo

I was looking at 70.3 Vichy, but costs are high when you consider the travel etc

Vichy is pretty much always a non-wetsuit swim which comes as a surprise to - & stresses - a lot of triathletes.

Annoyingly I got a place for Celtman :man_shrugging: which I had to commit to last month :man_facepalming: , but I’m hoping Slateman IM will run again in 2027….:grimacing: :

I’m not sure France or Lanza are in the UK :thinking::joy:

Agree with @gingerbongo it was a great little event, well organised at a decent venue. I camped at the lake for the weekend and did the Open Water swim on the Saturday - some slight course measurement issues but all sorted for the next day!

Roads were quiet, although this was the September event on a pretty blustery day. A hot day in May could be different. Some truly rural roads, you can scavenge plenty of spare bottles and @gingerbongo 's tool kit from the hedge if you fancy it. I wasn’t in good run shape so found it a slog, but the twists and undulations at least made it interesting.

I just stuck Lanza & IM France in as they are popular ones that UK folk may want to take into account for planning. If you like a hilly spectacular bike course, Nice is EPIC! and such a fab easy to get to venue, logistics are soo easy.

ooooh… sounds interesting :thinking:

SW smackdown anyone?

Edit: just checked out the bike course which is described as “Cornish flat” and goes through the village of Praze-An-Beeble twice. £99 entry. What’s not to love? I think I may be in.

“The 2026 Slateman Ultra Triathlon is now open for entry!

Starting and finishing in Llanberis, this isn’t your ordinary triathlon. Swim the cold waters of Llyn Padarn, bike over mountain passes, and trail run through the rugged quarries of Dinorwig. Make the cut-offs, and you’ll summit Yr Wyddfa (Snowdon) before the final push back to Llanberis.

This is not for beginners.

This is not for the curious.

This is for seasoned triathletes who crave extremes; who want elevation, exposure, and a fight against the elements as much as against the clock.

Entries are now open with instalment plans available. “

I’m hoping folks will support this / spread the word. And hopefully it’ll run again in 2027. Imp pressed that (un-inclement weather permitting) you get to summit* Snowdon, like on the Brutal Xtrmeme Tri’s in Sept.
* :thinking: That’s on the run btw, not the bike :sweat_smile:
