I've been doing 20% hills on a 28 cog at the back. The bike has got a long cage 105 derailleur, but it would have been fine with a short cage. Better probably, as they are easier when changing punctures.
With the 28 cog I'm spinning the wheel if it's greasy, or doing wheelies if I sit down. Mind you, I was toasted when I tried the 20% hill after a 70 mile warm up.
Phil: it's not a mass start, it's 4 waves. - go in the water, and get the water inside your wettie. Thrash about a bit, then choose where you are going to start from. -if you want a practice for Wales, probably start in the middle for a bit of a fight.
I'm doing Wales too, and I'll be black and yellow for this race.
little unlclear how the path from exit to T1 will work - its not exactly bare foot friendly.
They will usually lay carpet over such things as gravel paths and roadways between the swim exit and T1. Sometimes they even carpet the bit between bike dismount and racking in T2, because the fast end of the field do that in bare feet too.
OH that's a grim photo. I presume that the sign says Passing Place. There didn't seem much appetite for it!
If it's any consolation, we were suffering T shirt and casual shorts weather yesterday. I spent the day painting the fence and gardening. I should have used a bit of sunscreen, as my "wide parting" seems to have caught the sun a bit.
Planned training tonight is either a run, or bike on the rollers for an hour.
