In reply to Southvillain:
I'm also surprised by the implication that Fin and Tim's SkiMo round somehow supplants Dan, Jon and Paul's winter running first. It doesn't because we're comparing two different disciplines, so Dan, Jon and Paul still hold the record (or FKT if you prefer). Helen's round is actually only the second known sub-24 winter completion wholly on foot, with Mark Harris and Adam Harris's impressively fast (15 hours 45 mins) March 2016 effort sadly not making the December/January/February requirement. This is why I said the winter Tranter's still a huge, underrated/overlooked prize and why Helen's achievement is so significant.
