  • I'm considering there and back, fixed - naturally, with a train ticket from Ipswich in case I need to bail.
    Gear wise I commute on 48:16 but was going to drop to a 17t for this or would 18t be more sensible? Presumably people ride slightly more slowly in the dark?

  • It's flat the whole way and if there's any wind it tends to be from behind, so ride your normal gear.

    I wouldn't enjoy 80GI, 72 and an 18mph average is my favourite for the ride but I'm a bit feeble.

    Just checked the GI I was running at the time... 47:17 = 72.6 GI. Yeah, that was perfect.
