I would have posted earlier but didn't have many details.
A fantastic performance from a couple of young lads and a young support crew. Given Sasha won Carnethy 5 over 50mins of racing in Feb, it just goes to show that a good runner is a good runner. The lad's got ball the size of space hopper to have a go at this as his first proper 24h jobbie though!
Its not about squeezing the time down - its a 24 hour challenge to see how many Munros you can bag within this time limit. Adding Braeriach would be the obvious next step to increase the tally to 33. But you're quite right, an attempt in June might allow more ground to be covered.
Normal ways to break 24h records are add another peak, or complete the same route in a quicker time.
Sasha states that the Braeriach leg is about 1h extra running, so there is some scope there. There is also the scope to go faster. Often there'll be tactics at play and decission points to make, whether to add or to try and go faster.
