I've been waiting for this thread to appear. We'd like to repeat last year - I had a lovely time doing the race at Outlaw last year and Mrs Cheggers and the Cheggers Children really enjoyed doing the feed station. They genuinely are mad-keen to do it again so:
List of willing volunteers Barley Sherpa Dave Frags (+ No1 son) Jen Hart Tea Pot One (Bacon sandwich Queen) Rocco Allsortss Podds? Pingu Bristolsparks missus? Button Mushroom missus (+2 Mini Pirates) Cougie & Mrs C Bobs Your Father? Mrs Cheggers & 2 Cheggers children
If it were me I'd swap some days around. Do something from another day tomorrow and put the 4hr bike on that day - if it's feasible. That said, I think ice is likely to be a problem for the next few days.
Robbie - I'm lucky in as much as I'm using a Kickr which talks nicely to the iPad and a bike with a split in the seat tube (which I wouldn't want to use on the road) and that has the Wahoo Blue speed cadence on it and it all works well.
I think (but I'm not 100% certain) that an iPad lightning to 30 pin adaptor and a Wahoo ANT+ key will get the iPad chatting to Garmin ANT+ sensors but I'd punt around the internet (Rainmaker site?) a bit more to check I'm right before you committed to anything.
