I'm doing a triathlon in early spring & need to make a start on my training. I run 2-3 times a week us ally 5-6km sometimes a bit more but slowly & have historically done lots of cycling but not so much recently & my swimmer no is rubbish as I'm knackered after a length of crawl but start lessons in January so hopefully that will help 
.
I've looked at the finish times from last year's triathlon and it is more serious than I've done in the past plus a smaller field so I need to seriously improve in all 3 disciplines to hold my own (or at least not come last
). The event is 400m pool swim, 25km hilly cycle and 8km run so not massive but I need a plan to get me started and looks my at work/DC commitments reckon I can do something like this:
Monday: 30-40min run
Tuesday: 25/35km cycle
Wednesday: 20-30 mins swim
Thursday: 40/45 min run
Friday: cycle + swim or run (can make this sessions all 3 if I miss one earlier in the week)
Saturday: HIIT exercise class in the morning then swimming lesson PM
Sunday: rest
Once I've built my fitness up a bit and shred the few winter pounds I've gained recently I will look to do a more focused training plan (8 weeks beforehand?) but does this sound ok for the first 4-6 weeks?
